Last year around this time my Channel Master 4228 antenna was no longer picking up the signal for WCBS TV 2.1 (broadcast from the Empire State Building) at the usual 90+ %. All the other stations were locked in just fine with no unusual drop in signal. It was not until around April of 2010 that the signal got back up to the 90+ range. My back up antenna was an old UHF bowtie that I could switch to but that also experienced the same issue.

Well it happened again this year. Within the past week the signal dropped again on the CM4228.

The good news and relevance to this forum is that instead of that bowtie UHF antenna as a backup to the CM4228, I have my recent homebuilt GH6 with Narods. Well I am happy to report that WCBS TV 2.1 did not lose any signal strength on the GH6 at all. All channels remain locked in really well.

I guess it is an unexplained local anomally for me but the GH6 has proven to be a great build for us amatures and better than the professionally marketed antennas out there. Even the great CM4228 is being out performed.

Is that an original CM4228 you have, or one of the newer CM4228HDs?

Glad to see your situation taken care of by your GH. :)

Yeah. It definately sounds like the leaves have something to do with it. Normally, when the leaves fall, reception gets better for most. My guess is you have a multipath issue that is blocked by the leaves. Also the GH is mounted where the house could be blocking the multipath signal or maybe the big heatalator pipe behind the GH is knocking away the multipath signal.
