Default antenna or DSL or ??

I have 3 tvfool reports, one for all stations at 10', one for new digital at 25' and another at new digital for 50'. I also think that TVO/cbc has a relay station across the valley, so that my be where I am getting my strong signals.

Please use these current TVfool charts; I discovered that Google and tvfool had my location approx 3 miles and considerable height off.

Accurate maps are below:

In your location I'd install a 91XG UHF only fixed at Toronto plus a high band VHF only such as a Y10-7-13 on a rotor. You'll need a preamp and the Winegard AP-2870 will also add the VHF and UHF antennas together.

This won't get the analog stations on low band VHF, but they're probably going away soon.

Dear Tower Guy:

thank you very much.

The TVfool report doesn't show much difference for the various heights, but I gather it must clear the trees?

Will the rotor recommended stand up to the winds, or will I have to plan on replacing every so often?

(I have a friend who will let me have a 50 Delhi used tower of the type that attaches) and I may be able to get permission to attach it near the chimney; I assume the upper reaches (house is story and a half) would have to be guyed?

If the UHF antenna is aimed at Toronto, the rear corners would be facing directly NW into the wind (which probably will help with snowload); will that be a problem?

Finally, what expertise (what questions to ask) should I look for in deciding on someone to hire to put this up?

Thanks again

Clearing the trees will reduce the number of dropouts.

The VHF antenna is small and should not be an issue for the rotor, but I'm not a rotator expert.

Don't worry about snow or ice on the antenna. You might break one every 10-15 years, but that's cheaper than trying to do anything about it.

I don't know the Delhi tower, but in most cases you would use a house bracket as high up as you can. Go up another 10-15' with the tower, next is the UHF antenna, followed by the rotator, then a 5' mast and finally the VHF antenna.

Default in the fringe

Hi everyone,

I am in upstate NY and looking to cut the cord. My TVfool report looks like this:

eddy st
greenwich, NY 12834

I would like to grab a couple of Albany stations and maybe a New England station or two for NFL reasons

Please let me know if you have any recommendations!

Of the first 5 stations listed, only WNCE is actually on the air.

There is one New England station that's possible, WVER.

For the Albany stations you have two choices:

1. A large 2-69 antenna such as Winegard HD7084P or Channel Master 3671B.

2. Separate VHF and UHF antennas such as a Winegard HD5030 plus an Antennas Direct 91XG.

In either case a preamp is needed, the Channel Master 7777 a good choice.

Thanks TG! This might be a fruitless avenue for only a station or two. i appreciate the reply.

You should get all 7 digital stations from Albany. With subchannels, that's about 20 total.

Thinking of cutting the cord, but not sure what equipment I should get. I had been focusing on single antenna options but after stumbling across this thread it seems dual antennas are a better option. I'm open to suggestions and appreciate any help you can provide.

Default Off the back 4228hd reception in Ottawa Canada

Good day gents,

First post here, but i've contributed to other forums and have worked a lot tweaking my OTA setup since summer 2010.
Post-transition (sept 2011) in Canada the new channels in the 30-40 range coming off the back of my 4228hd are not that great. I'm wondering if picking another antenna would lead to better off the back reception.
My antenna is pointed at WNYF ch18 uhf(153 true) and I'm getting channels uhf 30,34,40 off the back at 287 true.
my TVFool:
(cannot post a URL yet. postal code: K1W1K1, elevation: 35 feet
EDIT: I added a screenshot of my TVFool report)
I've got a 4228hd with cm7777 preamp on the roof, hooked up with Quad Shield RG6. I also have a Delhi VIP-302SR in the attic. At the moment, I have an RG6 cable going from the attic to the cm7777 on the roof, but in time I will be moving my Kitz KT200 next to my VHF VIP-302SR in the attic. The setup feeds different Hauppauge PC tuners in computers. My best tuner is a 950Q, it sits with a 2250 in my main living room TV setup.

I would prefer to continue being able to pick up WNYF which is almost reliable all the time. But worst case i could trade this off for better off the back reception as long as I can still get WNPI & WCFE reliably like I do at the moment.

Right now I am thinking about the HD-8800 seriously, but I would really like your feedback on any other options. I understand a high front to back ratio can be regarded as a good thing, but in my case I have a feeling it is NOT a good thing.

You will need an antenna with a good F/B ratio to pick up WNYF on channel 18. This is because CITY on adjacent channel 17 is predicted to be 50 db stronger. Many tuners start having problems with 30 db adjacent channel stations.

TowerGuy, I'm still thinking about a very directional antenna for UHF only, so I agree and expect the front to back would still be relatively high, but i am hoping for a little bit better off the back reception. The main local Ottawa towers are Camp Fortune (CF) and Herberts Corners (HC) coming at 287 & 186 degrees true for me. The lower power UHF channels from CF are causing me troubles.

Would it matter if I pointed out that City (HC) is not coming off the back but is 33 degrees south of WNYF where my 8-bay is pointing ? Does F/B ratio have anything to do with towers side by side like this ? I thought it mainly affected front vs back reception.

So I'm still looking for something with a short beam width (maybe even shorter ?); that actually helps tune down City a bit since it is not catched at full gain (33 degrees off). Even better would be if the antenna would be near a NULL at 33 degrees to the right of the main lobe to balance things out.

But really so far my experience with a 4228hd and a friend experience with an HD8800 has been allright pointing to WNYF, with about the same angles between City and WNYF. I am really after better off the back reception. Thanks for the feedback so far !

Here is the polar pattern for the old Channel Master 4228. http://www.hdtvprimer.com/ANTENNAS/cm4228.html Note that the off axis performance at 33 degrees varies with the channel. Other 8 bay antennas will have similar patterns, but I wouldn't trust the pattern enough to make any installation or buying decisions.

I've seen polar patterns of the 91XG that suggest that it has an extremely high F/B ratio, but I can't find the graph posted anywhere.
