If one picture is worth 1,000 words then this ought to speak volumes. Here is a shot of the $85 Winegard DS3101 1-meter dish pictured alongside the new AT9, both chimney-mounted. I put the 1-meter Winegard up about 5 years ago expressly to get rid of rain fade. Results have been as expected. We do still experience an occasional brief fade, but it's literally got to be raining buckets.

Wow! That is my dream setup. Could never do it because of trees. I noticed it is in the back of your house so no nosey neighboors complaining. Awesome setup.

Check the FCC regs.
Homeowner's Assns, zoning, etc. are all usurped by the FCC reg which if you read it allows up to a 1-meter dish. I think what might be unclear is whether you can do what I did and have a second dish and the OTA antenna. Granted there's something to be said for being able to do it in the back yard and thus more or less out of sight.

Trees? Yeah, we got a few of those too. See photo below:

What are you hitting with that Winegard DS3101?

Probably 101, which from his location is quite high in the sky.

I was wondering because I could do a similar chimney mount but the dish would almost have to be on its back to get over trees. I believe I'm about as far south as he is here in New Orleans.

Google Earth says I'm at 29-41-22 N and 95-39-43 W and yes, the big dish is pointing at the 101, since that's where most of our viewing is. I'd have to say that's the best $85 I've spent in a good long while. There's no LNB with it, but it has a universal mount so you can reuse the LNB from an 18" dish.

The trees in the photo are a tad less than 20' in front of the dish. Shooting over is no problem tho. Remember, the DS3101 has a 24 degree offset, so it's actually aiming 24 degrees higher than things might otherwise appear. At my location the 101 bird is 54.84 degrees above the horizon. As big as those trees are, they're still going to have to grow another 10' before they become a problem. That's when we give the starting rope on the 20" Husqvarna a couple tugs and do a little "pruning".

Living in hurricane country, a good chain saw is almost de rigueur. Yeah, 20" is a trifle big for residential applications but it makes for good bragging rights at the occasional neighborhood BBQ ;)

I just picked up the same OTA I love it 24.99 and I get all my HD stations 25 miles out through a thick dense forest. I really need to get a site survey tool to see how much I would have to cut off trees to get reception from 1 5 LBN dish.

Here's a better photo showing the dish mounting angle and it's proximity to the trees in front of it.

Can you explain how the winegard dish is successfully joined to the AT9 dish without losing any signal. I am struggling with a bad rain fade problem and Directv is hopeless in this regard. Thanks!

Good Question!!

I've wrestled with that somewhat myself. Presently the solution, tho not elegant, is nonetheless functional. Since we needed a second coax to the receiver for the OTA stuff it was only logical to diplex OTA in with the old existing coax from the big Winegard and then use a simple A/B switch (Pico-Macom #AB-4). A second diplexer peels off the OTA signal ahead of the A/B switch to go to the OTA input on the H20 receiver. The SAT input of the H20 then goes to the "common" output leg of the A/B switch.

What I've honestly wondered is if it would be possible to take apart the main LNB of the AT9 and disable (remove) the wires for the 101 and externally cable-in from a second external dish.

Sometimes necessity is the mother of invention and success is adversity's child.

What kind of signal levels are you getting now?

I see you have a lovely cottonwood. Our back neighbor has one and it gets in all our pools and clogs the filters. Do you every get any signal lost from the cotton wood blanketing the dish?

Hey Cap..(I also posted this question on the typical signal strength thread.) I live at the New Jersey Shore. I just switched from Dish Network. I think I've only lost the signal about five times a year mostly during thunderstorms. With the new 3 LNBF DTV multi dish and R15 I'm running anywhere from 81 to 100 on 101 on a clear day. I have experienced rain fade during thunderstorms, but signal comes back pretty quickly. it's usually due to the dense cloud cover which occurs before the heavy rain. Can this dish use further tweaking?

101:

1-8 90 82 96 88 87 90 81
9-16 88 88 88 96 90 87 92 84
17-24 90 100 91 92 90 86 91 86
25-32 87 95 92 0 93 86 91 83

Maybe and maybe not. For your location your signal levels look pretty decent for a small dish and some occasional rain fade, even with my big Winegard (which doesn't happen very often), is normal.

That isn't a Cottonwood. It's a Crepe Myrtle and almost as messy. No problem with blossom accumulation on the dish.
