I would like to ask why this was so for you?
I'm not contesting your findings, I'm just genuinely curious.
I owned both the DTT-900 with newer tuner (Not original Sanyo tuner), and the newer DTT-901 with APT (Analog Pass-Through). I live with a major city between me and my broadcasters "Antenna Farm".
I'm also buried in thick woods
I am also in the flight path of an international airport. Neither Zenith would hold ANY of the 30 channels/subs during air traffic. Not one channel. The two Channel Master CM-7000's I traded them for never miss a beat. Ever.
I will say that I can easily overload the CM-7000's if I turn up my distribution amplifier a touch to much.
Did you have an overly strong signal or a lot of amplification during your test perhaps?
The CM's get a bit edgy if they get to much RF.
My equipment is the largest RS boom antenna they could ship before the max length was lowered by UPS with a mast-mount Channel Master CM-7777 preamp. I have the VHF and UHF active elements seperated to utilize the seperate inputs on that model. RG-11 Quad-Shield runs inside to an (old) Blonder-Tongue distribution amp that has variable gain. I remember taking the inside stuff off and connecting both Zenith's directly to the CM-7777 power injector where the downfeed enters my home as a test, they were no better.
To others new to this topic the Zenith units are very nice units inside and out. They are well built. I feel they are a very close second. I still recommend them for the second coupon in spite of my own experience. An overwelming number of people have good success with these units.
They did find and show *Almost* all of my available channels. Only missed a few weak ones. They just didn't do airliners at all for me. I'm the exception installation.
Oh, and if your on a power grid that "Blinks" once every night and every afternoon like us, expect lockups on the Zenith's. Very fustrating if (like me) you record to watch later and skip the 52-55% of each hours commercials! During the time I had them I used a UPS on the newer 901, and I soldered larger electrolytic capacitors into the earlier 900's power supply so they wouldn't freeze up... Just a quirk I thought I should note for people...
