So I was replacing the mast on my OTA HD antenna, which consists of 2 CM 4228's mounted one over the other and connected together, and despite the greatest of care, I dropped the mast and bent the heck out of the 4228's. One got it worse than the other, but both were bent up to some degree...

Currently, it's mounted through 2 same-diameter holes drilled in the top and bottom 2x6 rails of our back deck, with the bottom of the pole anchored to the deck itself. So the bottom 3 feet is supported by the railing structure (which is plenty sturdy, believe me) and the remaining 6 feet of...

One more thing - The original reply mentioned securing the antenna and stiffening the mast against wind. My antenna is definitely secure, and the mast securely mounted, but it is only a 1" diameter metal pipe that extends about 7" above my deck rail. Given that, it defintely will sway about...

So I went out and adjusted the two 4228's, and an interesting thing happened: When I aligned both of them so that they faced precisely the same direction, at a compass heading that appears to be somewhat in the middle of the 280-300 spread between my OTA stations, I was able to get good signal...

Thanks for the feedback. I'll keep tinkering and agree with your statement that it's oftentimes more art than science. I also know that I'm asking for more issues when I combine 2 antennas into a single downlead, but is there a better solution in this situation? My old DB-4 had enough...

I live in Atlanta very close (approximately 5 miles) to the OTA transmitters. So close, in fact, that they are in two different directions: UPN, ABC, and NBC (which is VHF, Ch. 10) at 280 deg. and the rest at 300 deg. My backyard is about 20 yards of open space leading to a pretty solid wall...
