I live in Murfreesboro TN 40 miles from Nashville TN I receive all the the stations crystal clear. I started out with a CM4228 only received 1/2 the stations and would loose them all if it rained or snowed. I made improvements on my antenna it was receiving all the station but still the smallest thing like rain or snow or what seemed like nothing at all I would loose all the stations or some of them. I bought several more antennas including 91XG tired them all nothing worked much better. 2 antennas in parallel are worse. 3 antennas connected to a combiner does not work either. Build an antenna for each TV in the house.

I built my own antenna from what I knew to be the best way to make it work. The larger 48"x48" reflector screen was a big improvement. Smaller holes in the reflector screen worked better too. Changing connection wire to low resistance low skin effect wire #14 copper was an improvement too. Changing bow tie wires to solid metal was a very big improvement. I put a balum on each 1/2 of the antenna = each 4 bay section used 18" coax to connect them to a T combiner then use 1 coax from the T to the TV WOW what an improvement. No matter what the weather does, flash flood, blinding snow, wind, fog, i get crystal clean reception all the time. I took my antenna on a road trip to see how it preforms i get very good reception 70 miles from Nashville. The antenna even picks up channel 5 which is real channel 5. I have good pictures I will upload. I wish I could upload pics to this forum without uploading them someplace else the linking them here. Mount bow ties to 1" PVC pipe. Mount PVC pipe to the wooden frame. Mount reflector screen to back side of wooden frame. Reflector screen should be 6" from Bow Ties. I learned a T splitter connected backwards works just at good as a T combiner cost is 4 times less.

Gary 350 I can not believe that the 91xg did not beat them all .on the 91xg did you did you happen too try a amp on in like the channel master 7777amp .
Becuse I don't believe that the 91 woked so poor and in Massachusetts .it doesn't matter where I put up the 91xg WITH the channel master amp it just seems too kik but over all the rest of the antnnas,

Thanks everyone. Just seeing this thread again. Some thoughts:

This morning I was over at the house early, and as it just so happens my father-in-law showed me how he gets CBS on both ch. 5 and ch. 25! Again, this is with the 2MAX only a few feet off the ground outside. 25 does come in better, but not perfectly all the time. But even the 5 translator came in sometimes.

I have tried to see where stations are planning to move. But haven't run across a concise report. And I've read that some are going back to VHF-LO. Quite frankly that's depressing if we have to revert to those huge antennas more prone to wind damage etc. And I really don't want to invest time + money getting it right, only to have the game changed in a year or whatever if a few move to VHF-LO.

Sorry for the rant.

I need to clarify that I never intended to compare them. The 2MAX was purchased by someone else as a stop-gap measure for indoor use. (When the connection to the old antenna up on the mast got broken -- I think my father-in-law rotated the mast somehow and snapped the wire?) Only when the 2MAX proved useless did they rejigger it for outdoor use, where it's often passable.

Regardless of whatever we do, we'll still have to take down the old mast that's shoved into the ground and secured up to to the side of the house. My father-in-law is convinced we'll be able to pull it out of the ground and with some help, not have it all crashing into the neighbor's house ...

... all of which is to say, I'd like to try the old antenna FIRST, albeit with fresh cable etc since he said that was "pretty good" reception previously.

The UHF stations are going to be easy. Something like a 7694 with a preamp would be your minimum, stepping up to a 7698 for its relatively superior VHF reception would be reasonable but you'd still be dealing with a 14' long antenna.
Today's situation in Lafayette, TN does not seem very different than what I had to deal with in Woodstock, GA trying for ATL stations. Similar distance to towers, similar troposcopic concerns. Similar issue with PBS being on ch. 8. Similar issue with trying to get a second VHF-HI station.

My first attempt was a 7696 on a 5ft mast on the roof's peak. No VHF reception at all (!) and several UHF were weak. I tried adding a 269 preamp, and later either a 7777 or 7776? They were likely too strong, or too noisy or both. Lots of time and money wasted.

My final workable solution was imperfect, but passable: a 10 ft mast up on the roof, now it was probably a good 60ft or so from ground, with both 91XG and 1713 (no preamp). Honestly I think the 1713 did a better job than the 91XG did. Both antennas lost or got bent a couple elements from wind/rain storms in less than 5 years. That pissed me off, as neither are exceptionally long antennas. And then the mast started to rotate on its own, despite tightening the crap out of it a second or third time. I do not like tripod mounts.

I likely did not separate the antennas enough from one another, but I did have them pointing in slightly different directions since the VHF stations were a couple degrees different from the rest.

What's with Denny's Stacker? Similar price to the 8200U ... but with less concern about wind damage? I know the Stacker is his baby, but he does claim it's quite a bit better for real RF 8 than either the 8200 or 7698.

I also see he sells a VHF-HI antenna, HBV 2500.

Thanks Gary; I don't pretend to understand all of that but can certainly appreciate the effort needed to hot-rod an existing design.

From one of your pictures ... use only twist-on connectors, why? I already have a good crimp tool and connectors for RG-6, from a previous project.

Yes like I did too the 8200u cut off the uhf off of the 8200u,and put the 91xg in place of it ,which works great with a channel master amp for the uhf,
And one for the hi and low vhf,I was told that it would not work but I will tell you what happened,works quite well uhf 80miles with it and the vhf too at a 100+miles,

CM4228 has reception about 12 degrees each side of center but 91xg is only 5 degrees each side of center. Sometimes weather makes the signal drift away from 308 degrees which is where my antenna is aimed. If the station signal drifts off to 315 degrees 91xg will loose the signal but CM4228 still works. I have a fixed antenna I do not want to buy a rotor. You should buy several antennas then try them all, keep the one that works best sell the others on ebay to get your money back.

I live in Murfreesboro TN 40 miles from Nashville TN.

All the big cities have the same stations for the exception of small local stations. Memphis, Chattanooga, Nashville, Cookville, Crossville, Clarksville and other towns all have, ABC, CBS, NBC, NPT and others. Try to get all those stations from the closest town to you.

15 years ago I started out experimenting with TV antennas. For me CM4228 worked better than 91XGs and DB8 was better than those. There may be better antennas available now so check them out.

If you buy an antenna you can make improvements to it that will make it 2 and 3 times better but it is cheaper to built your own TV antenna and save money.

You should check TVFool for other town that will help you learn what frequency range your antenna should be for best reception. I do not have a rotor all my stations are in an area 12 degrees both sides of center for my antenna aimed at 308 degrees it receives everything from 295 to 318 the 91XGs does not work for me because band width is only 5 degrees each side of center it will require a rotor.

I built my antenna to be over kill so signal is never lost no matter how hard it rains, snows, fog, wind, etc. nothing makes me loose the signal I have crystal clear reception for 70 miles.

I tried using 1 antenna for 2 TVs it does not work as well at 1 antenna for each TN.

If you buy a DB8 or CM4228 put a larger 48"x48" reflector screen on it with smaller 1" or 1/2" holes your signal will double. If you buy or build a beam antenna like 91XGs put a solid metal reflector on it that makes it work better & the shape of the reflector makes it work better also V shape with 90 degree bend seems to work better than C shape or l flat shape. If you experiment you will see different shapes work better for different stations.

I started out years ago buying lots of antennas to see what worked then reselling them on Ebay to get my money back for antennas that did not work for me.

An antenna outside works 2 times better than an antenna inside the house or in the attic. If you move your antenna around all over the yard you have find hot spots where the antenna works better in one place than other places.

If your a long way from the stations every little improvement helps you with better reception.

Be sure to test all balums = antenna matching transformers some brand new ones do not work at all and some work better than others.

Here is my antenna. Aluminum roll roofing from Home Depot makes good 1" x5" bow ties 9.5 to 10" long. #12 copper wire has low resistance for connecting wire. 48" long piece of 1" PVC pipe in a good insulator for each row of 4 bow ties. The 1"x2" board wood frame is very light weight and works good to hold the PVC pipe and reflector screen. Reflector screen needs to be 6" from the bow ties.

If you buy a roll of wire and roll of 10" aluminum you have enough to make several antennas. I usually build several antennas each time 3 to 5 sometimes 20 antennas. Lots of people refuse to believe you can get free TV from an antenna so I set 1 up at my yard sale to prove it works then sell all the antennas for basically my cost just to get my money back. There are lots of people than can not afford cable or an antenna.

Make sure your coax is new because old cable is often not as good as it was when it was brand new. Make sure cable from antenna to TV is 1 coax not several coax all connected together. Make your the 2 balums on your antenna are in phase with each other test each 4 bay side using field strength meter on your TV.

Chain link fence top rails make a great antenna tower the ends slide inside each other.

YOU did not read what I wrote. 91xg has narrower reception 5 degrees each side of center compared to CM4228 which is 12 degrees each side of center. I do not need a rotor with CM4228 but I do need a rotor with 91xg to receive all my stations. One time I built a manual rotor with 2 ropes and 2 eye bolts. I ran the rope through an eye both to each side of the antenna. I put a knot in the rope to stop the rotation of the antenna at maximum left and maximum right. When knot in left rope hits the eye bolt it stops. Same thing for right side. When I pulled the left rope the left side of the antenna rotated to the left. The right rope pulled antenna to the right. LOL it actually worked good. My geographical location is very good for not needing a rotor if my antenna will receive all the stations between 297 degrees and 312 degrees there are 44 channels at this location.

A better antenna is much better than an amplifier. You can not amplify a bad signal and make it good. A poor antenna signal stations will fade IN and OUT if there is no signal you can not amplify it.

My home built antenna receives a signal 2 times stronger than the 91xg

There are other stations i would like to receive like channel 6.1 to 6.7 at 359 degrees 25 miles away. This is a small town very low power station with very good programs a 91xg aimed at 359 deg using a selector switch on the TV to switch to different antennas will work best for me.

Looks like I already answered this 3 times. I guess I should start looking through the whole thread before answering.

Sorry, I guess I somehow missed the answer to my question 3 times? My apologies. Crimped, twisted-on, whatever.

Nice antenna design.

I think the baluns you are using are very inefficient. Your pictures show they have the crimped on spade connectors.

See if you can find some of the original Channel Master baluns, as the ones you are using are very lossy.
