So I spoke with a rep today about the HD Stacker and they indicated that the antenna has a UHF gain of 16.2dB (they stated that one can test in a number of ways, but the representative indicated that the 16.2dB would be consistent with how Winegard would test an antenna).
Based upon this information, the testing that I did Saturday and Tower's info on how much gain (up to 6dB) I could have been getting due to wave reflection off of the pavement it would appear that I would need an antenna with a UHF gain in the range of 22dB to receive in my current mast location.
From Tower's earlier post it appears that the best UHF gain on the commercial antenna were in the 16-17dB range.
Unless there is other test data that would indicate that the UHF gain on the HD Stacker is less than 16dB it would appear that my best option would be to relocate the mast. However this would need to wait until at least next spring/summer.
Based on keeping the antenna at the current mast location:
It is possible that upgrading the pre-amp from the Wingard LNA-200 to the Kitztech KT-200-COAX could reduce noise by 0.5 to 2 dB however based on the testing this doesn't appear to have a high percentage chance of solving the problem.
I'm not opposed to trying a two antenna system; however before investing in that test the household accountant wants decent odds it may work.
Based on the information presented, do folks think that trying a 2 antenna setup as previously discussed by MikeBear and Rabbit in posts #7 & #9 have a decent chance of success (at the current location)?
Thanks
