About 6 months ago I put up an RCA ANT751R. My antenna points directly through a lot of big trees. I'm amazed at how well it works, really, but I wish it could be a bit better, although I'm convinced I have it aimed well. On windy days a few channels intermittently falter with seemingly malicious timing.
I recently asked a question via the "Ask an RCA engineer" facility on their web site. My question was essentially, "What's the ideal vertical stacking height for the RCA ANT751R". Their reply was, "You can find that on the Internet".
I've tried looking at several resources and came away wondering if it's worth the effort to attempt joining 2 antennas. There's the phase cancellation potential. Where do you put a single amp? How much gain is likely.
Has anybody had any luck stacking antennae? Any resources you can point to that are "lay person friendly"?
Reception through trees can be challenging. Movement and/or wetness can cause problems. It would be helpful to see an picture of the horizon to gauge he impact of the interference. I happen to shoot through red pines. They are sticks with tufts of green at the top that sway relentlessly year round. I have found that an antenna with a broader receiving/reflecting area holds the picture better than one like yours. If you would like to post a tvfool.com report for your address (use the gps coordinates of your antenna for best results), I would be happy to take a look and let you know what I think.
