Default Antennacraft super g-1483 deep fringe

I finished installing my new Super G-1483 Hoverman this weekend. It replaced a set of verticly stacked 91XG's. The performance of the 91 XG's was great, but with the verticle spacing I didn't have enough room left for my antennacraft Y10-7-13 VHF above the rotor. The Super G-1483 does slightly outperform my stacked 91 XG's, as I had a couple of stations that would freeze or pixel ocasionaly when I was using my DVD recorder, and that is no longer an issue. My Zip is 98596, I am 71 miles from the Portland Or stations, and this 1483 is over 40' off the ground. This antenna is not for the weak at heart, I had to work on it quite a bit right out of the box. The build quality is marginal, but nothing that can't be fixed with epoxy, and some effort. It greatly outperformed the 4228 HD I tested as well.

What a shame to manufacture such a good performing antenna with Radio Shack build quality. Do you think it will withstand the elements well in your area?

I do, I ran the mast all the way up and put epoxy on all the dipoles after folding out. I talked to a couple people before installing and bird's landing on the top dipoles is an issue, some people wire tie, tape or glue, I opted for the epoxy, and did all of them. Time will tell if it holds up???

That Super-G antenna is an array of 4 Hoverman Antennas (1964 version). I didn't think AntennaCraft produced it anymore. Where did you get it?

Speaking of AntennaCraft and Hoveman antennas, where the heck is the promised U4500? It was supposed to be available in the Spring of 2009 but it is not yet available. Maybe they meant Spring in the Southern Hemisphere.

I talked to one of their engineers about the U4500 before I ordered the G1483, and the U4500 is on the back burner for now. Summit Source is the suplier, according to Antennacraft they build it for Summit as they order in quantity. If I had it to do over, I would ask summit to remove the 5' mast from the box and throw it in the trash, as everything is shipped loose in the box and the 5' mast does some damage. It appears that they are shipped to summit fully assembled, that's what it says on the box, factory labled by Antennacraft. The box is cut down and and re-sealed, I assume saving them some on the shipping.

I will make a couple of comments, and then if you wish, I will keep my comments to myself.

From what I see, like you have said, is a old style antenna that has been reproduced by today's standards. With modern manufacturing technic's. They could have gone in one of two directions.

They could have used a positive lock stop like what is used on most all Channel Master antenna's. Or they could cheapen the antenna and make it as fast as possible. They choose the latter of the two.

Back in the 40's - 60's, antenna's had to be made big, because fringe reception of UHF was very hard to accomplish. In return for a bigger antenna you got more gain which helped the television or converter box to better receive the signals.

You have to remember that neither the superheterodyne receiver or the tube type receiver was any good at receiving UHF signals. 4 times the loss just in the tuner as compared to VHF.

The only problem I have with your analysis is that you are not comparing apples to apples.

You have to remember that with diffraction, a wave might have a spacing of as much as 5 feet horizontally between one good signal point and the next.

If in fact, your tower is in one of those areas, you will receive good reception. If it isn't, then it is a cracp shoot.

To compare this new antenna to your old antenna, you would first have to find two locations with the exact same amount of reception and put up a second tower which would not interfere with the first.

Put both antenna's at the same elevation and have two exact same tuners and watch both televisions at the same time or have a frequency meter that could measure power received at the antenna for both.

You have to remember that the old style signal strength meters are not compatible with the new digital television signals, due to the fact that with analog the signals were a constant stream and could be measured with the meter that was designed and built to measure it.

With the digital signal, the stream is transmitted in bursts and the digital signal hides defects which would show you how much signal is at hand.

Yesterday with a cold front approaching, I had zero signal strength for many good stations and I had a poor signal for some close stations that usually comes in with no issues.

Today with early morning tropo reception and a high pressure system approaching my area, I picked up one new channel and I have a strong signal coming from all my signals in the South West and West this morning.

Nothing coming from the North West, Cleveland Oh or the North - Erie Pa.

So if I put your new antenna up yesterday and I got no signal from the West, I might be inclined to say that this antenna sucks. Today if I put it up and I had signals that I did not have yesterday, I would say it was the next best thing since sliced bread.

I'm sure that it is a awesome antenna and that you have a awesome set up and I am glad that you posted your results on here and maybe some other people living in a fringe area can investigate it further in the future.

Thanks for the info.

I don't claim to be an expert, but the facts are as follows:
The 91XG verticle stack was on the same mast as my current set up, at the same elevation, and worked very well. In fact, I used it for almost 2 years.
It did not alow me enough room above the rotor for a VHF antenna, which I needed post transition as 8,10 and 12 in Portland went back to VHF.
This UHF antenna performs only slightly better than the 91XG's I took down.
I now have enough room for my VHF antenna and the Y10 7-13 is working very well for 8, 10 and 12 .
This set-up has been up since Sunday morning and I have had 0 pixel/dropout issues, even on my weekest channel 2.1 (43 I beleive)
That's it for the facts, the rest is my opinon based on past experience:
I don't recommend this antenna for everyone, if somone did ask me I would recomend starting with the 91XG, as it is light weight, inexpensive, and based on my experience works very well. If that doesn't get them the results they want, and they have a couple hundred dollars they can live without, the maybe try the G1483. I would recomend the 1483 over a verticly stacked 91XG setup, as I did not gain much when I added the second 91XG.
I would also tell them that this is all trial and error, and what works for one may not work for others.

Only possible problem I see is the distance from the idler to the top of the array is quite long and the Hooverman has a relatively high wind load.

I hope the mast is strong enough in a wind storm.

Even Summit Source claims 16DB gain for that antenna: it looks as if it calls for some further investigation, as, while it's large, it may be the answer for deep-fringe UHF reception. The spoiler here is that no one appears to make a deep-fringe VHF antenna any longer: Wade-Delhi stopped making them, and now AntennaCraft has stopped making the CS1100, which was the last deep-fringe VHF antenna on the market. The Winegard HD-5030 is not really suited to deep-fringe VHF reception, especially on Low-Band VHF.

I noticed that Summit Source charges $159.00 delivered for the G-1483, which is about what 2 XG-91's would cost. Almost $50.00 of that cost is in shipping. In my area, where I have a LOT of strong UHF signals, I doubt that I'd could take advantage of that the G-1483 can offer, but I can think of a lot of people who can use it's gain.

Stacking like TV antennas is a tricky business, and I'm not sure that everyone can take full advantage of all of the benefits of stacking antennas, as it requires a considerable amount of precision in the installation. It would appear that the G-1483 solves this problem by providing fixed relationships between the various elements, which makes it a bit easier to achieve repeatable results.

As I remember about the orignal Hoverman design, it had a difficult time covering the entire UHF band, which, at the time, went from 470 mHz up to 890 mHz. However, with the newly truncated UHF band in the US, the Hoverman design probably has some serious merit.

There is a canadian forum that primarily discusses modifications on the Gray Hoverman design. Some of their versions include high VHF reception. See: http://www.digitalhome.ca/forum/forumdisplay.php?f=186

Actually SummitSource is selling 3 different AntennaCraft G-1483 antennas. They should really give the 3 models different numbers.

First there is the 16-bay Super G-1483 that the OP bought. This is an array of 4 Hovermans.

Then there is the 8-bay Super G-1483 which is 2 Hovermans stacked vertically.

Finally there is the 4-bay g-1483 which is a single Hoverman.

Looking at the photos it appears that AntennaCraft have modified the original Hoverman design slightly by lopping 2 inches off each of the horizontal segments of the active elements. This makes the active elements 52 inches long (six 7" sements and two 5" segment) rather than 56" (eight 7" segments). This appears to be an attempt to shift the antennas range higher into the UHF range.

The 1970 vintage Hoverman (sold by Radio Shack) that I have was an even more drastic modification where the horizontal segments were shortened by 5" and the angle between the shortened segments and their adjacent segment was reduced to 90 degrees (from 135 degree). Unlike the AntennaCraft desgn, the four 5" lengths that were lopped off were not thrown away but were used as vertical elements. This antenna has given me good reception for all the UHF stations, analogue and digital, in the Plattsburgh-Burlington market over the last 39 years, ranging from channel 14 to 57 (real channel numbers). If I could find a new one of the same design, I'd buy it in a flash because it does the job that I need it to, it has low wind resistance and has stood up to harsh winter conditions including heavy ice build-ups. (There are no missing or bent elements.) Unfortunately the AntennaCraft 4-bay g-1483 does not look as sturdily built.

Apparently AntennaCraft only produce them for SummitSource. They are not listed on the AntennaCraft web site.

OTOH, the much-delayed U4500 is listed and if AntennaCraft actually produce it, you can expect it to be available through other sources such as Solid Signal.
