I live in Stony Brook, NY, on the north shore of central Long Island.
After a few months of playing around, I mounted a Winegard HD9095 UHF and a Winegard YA713 Highband VHF on a 20 foot pole on my back deck. A CM7777 antenna is also used. When this system is pointed toward the ESB, I get the following performance:
CBS 2 or 3 (RF 33 from NY or CT or RF 22 from LI) never anything
NBC 4 from NYC - sometimes OK, frequently nothing; NBC 30/35 from CT, better (if I turn the antenna N, then it gets very good, but I am listing only performance with the antennas pointed SW)
FOX 5 from NYC - sometimes useable, but not usually
WOR 9 from NYC - rarely useable
(I know these are all UHF stations)
ABC from NYC (RF 7) 100%, even with the 7777 removed
PIX from NYC (RF 11) 100%, even with the 7777 removed
WNET from NYC (RF 13) 100%, even with the 7777 removed
WLIW 21 from LI (RF 21) 100% with the 7777, 60% without
Channel 25 from ESB - same as WLIW
Channels 24, 49 from ct - useable with the 7777, nothing without
WNJN from NJ - sometimes excellent with the 7777, nothing without
My questrions: I can raise the antenna to my roof, about feet 15 higher (but not until spring); should I do so? (If I do, I won't be able to manually rotate the mast to get better CT or eastern LI better).
The antennas are pointing to trees about 50 feet away - how will that affect the signal when they leaf out? These trees are about 100 feet tall!
Should I recable the system so the 7777 is not used for VHF - it doesn't appear to be necessary, but how do I combine the signals with minimum loss, and I would then have two cables.
I have about 100 feet of RG6. I also have a cheap RS distribution amp, which doesn't appear to be either good or bad, except that it works as a splitter. I did these tests without it.
Another thing, usually the main WNET and WLIW channels appear as 13.3 or 21.3. They has the same content as 13.1 and 21.1 and, if I type in 13.3 or 21.3, I get the correct .3 subchannel.
