UHF and VHF from different directions, plus airplanes

[teaguecl]

I'm having some trouble determining the best antenna for my situation, any advice would be appreciated.
My TV Fool report is here: http://www.tvfool.com/?option=com_wr...5b946f88bbc5ce

I am really only interested in the first 7 channels on the report. It turns out am in directly in between the two towers of interest - they are 172 degrees apart from each other (one is at 121 degrees, the other at 293). I'm not that far from either tower, 13 miles and 7 miles respectively. It turns on that one tower broadcasts all UHF (channels 18,19,28,30,40) and the other one broacasts two VHF (8,10).

So it seems like I need a VHF antenna pointed at 293 degrees, and a UHF pointed at 121. My first attempt was to use a Winegard gs-1100. From looking at it's gain chart it seemed to be pretty good about picking up two signals that are 180 degrees apart (http://www.winegarddirect.com/pdf/spec_SENSAR.pdf).
It actually works OK. I see all the channels I am interested in, with a few notes.
1. The two VHF channels come in fairly weak most of the time.
2. I live near a small airport and whenever a small plane (cesna) or helicopter are within earshot, the signal drops out for 10-20 seconds.

I have tried placing the gs-1100 in two positions. First I had it about 12 feet off the ground in my attic, which worked decently but not great. Next, I moved it to sit on my garbage cans (so about 3 ft off the ground) outside. This position works much better, but I still get dropouts due to the planes.

What should I do? I've debated the following actions, but really don't know.
1. Try mounting my gs-1100 on the roof. I don't know if elevation will help at all with the multipath problem from the planes.
2. get a new omni directional antenna (RCA ANT800F ?) I think the omni might give me more problems with the planes than the directional.
3. get a different directional antenna that has a good pickup from the back side, but I don't know what model that would be.
4. Place separate VHF and UHF antennas on a mast, pointing in opposite directions. The only vhf antennas I've seen are huge (10 ft long), which seems unnecessary since the VHF signal is only 7 miles away.

I'd love to get some opinions as I'm not very knowledgeable about this stuff.

A premium solution would be an Antennas Direct DB4e + Antennacraft Y5713.

A Simple reception situation.

The signal strengths of Digital Broadcast Tv Stations are strong to moderate signal strengths.

Above the Peak Of The Roof in such a manner that reception is not , obstructed , impeded , blocked by the roof and building , install a , http://www.antennacraft.net , U8000 UHF channels 14 thru 51 antenna aimed at about 129 degree magnetic compass direction.

-----------------------------------

Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html.

Use a Real and Actual magnetic compass to aim antenna.

----------------------------------

Install a , http://www.antennacraft.net , Y5-7-13 , VHF high band channels 7 thru 13 antenna aimed at about 280 degree magnetic compass direction.

------------------

Connect the , U8000 antenna and Y5-7-13 antenna together with a , EU385CF-1s , UHF/VHF combiner.

Connect the U8000 antenna to the UHF connection of the combiner.

Connect the Y5-7-13 antenna to the VHF connection of the combiner.

The remaining connection of the combiner goes to the Tv/s.

---------------------------

A antenna system amplifier will most likely not be required for , 1 , 2 , 3 , Tv's connected.

For 1 Tv connected use No splitter.

For 2 Tv's connected use a , Holland Electronics , HFS-2D , 2 way splitter.

For 3 Tv's connected use a , Holland Electronics , HFS-3D , 3 way splitter.

Buy the , HFS-2D and HFS-3D , splitters at , http://www.solidsignal.com , or , http://www.hollandelectronics.com.

-------------------------------------

Here are some places to buy antennas and etc. .

http://www.ronard.com.

-------------------------------

Here are some above the roof antenna mounts.

http://www.ronard.com/909911.html.
Use the , ronard(911) , 5 foot tripod antenna mount.

http://www.ronard.com/34424560.html.
Use the , ronard(4560) , eave antenna mount.

http://www.ronard.com/ychim.html.
Measure around the chimney and use a , ronard(2212) , ronard(2218) , ronard(2224) .

-----------------------

As Always , trees and tree leaves , plants and plant leaves , have a Negative Effect on Broadcast Tv Reception and so do buildings and other obstructions including your own roof and building.

Some and not all Negative Effects are.

Absorbing and Blocking , Reception.

Multi-Path Reflecting Tv Signals Bouncing All Around.

The Best Practice is to install the antennas at location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own roof and building.

The Winegard HD 1080 is a VHF And UHF antenna that just happens to aim the VHF lobes opposite the UHF pattern. It's the cheapest and simplest solution.

Reports are coming in here at Tvfool of reception situations/problems with , KFMB channel 8 and KGTV channel 10.

The 2 edge path obstructions and air planes are causing multi-path and the air planes are causing moving multi-path.

The Y5-7-13 antenna is a directional antenna.

Directional antennas receive the best in the forward direction and less reception in the other directions , the directional ability of directional antennas to reduce multi-path , reflected , Tv signals bouncing all around.

And also reports of FM radio transmitter interference.

So this is the reason for the recommendation of , Y5-7-13 , VHF high band channels 7 thru 13 antenna.
