SOME TYPICAL CUSTOMER COMMENTS ABOUT THE PHEMT LNA's:
I've finally tested the 9254 preamplifier with digital television, full success:
- we get all the French channels now (in stead of half of them before)- we
also get all the Swiss channels (none before).
I received the 9253 yesterday. I must say that so far it is working
phenomenally.
It made a significant
improvement, and I am now receiving perfect pictures on all analogue
channels and only very occasional picture break-up on digital channels.
The preamp made a great improvement in quality of the received signals.
I was able to receive one channel that is running on low power with the
transmitting antenna mounted half way up on the tower about 90 air miles
distance.
I got this installed a few weeks ago. It made a huge difference. All our
digital uhf stations are 100-140 km from us. They all come in perfect with
no drop outs.
Everything works great!! I can pick up HD signals from up to 70 miles away!
I received the preamp system on March 31st. It was well packed and I
was able to install in early April. I waited about a month before writing you
this thank you note. I wanted to be sure that the system got a good
testing before I let you know what I think of it.
The preamp is wonderful. I use a large vhf/uhf antenna and a uhf
antenna. The preamp is hooked up to the uhf antenna and I can rotate
the system in all directions. Your preamp works great I can get over 50
Hdtv channels with it.I can only get 38 with the other antenna and a
different preamp. I have also almost no problems with hdtv breakup or
overload. Thanks again.
Preamp arrived today, works fine - super... Thank you.
I have only tested two (2) of the preamplifiers to date. The units
performed well enough to allow good reception (not perfect reception) of
three tv stations which previously had only fair reception. This increases
the number of truly watchable uhf stations to 9 of 24 detectable stations,
in a bad location, with a Winegard 9885 antenna and a Channel Plus model
DA-500A distribution amplifier. The distribution amplifier which has a
quoted noise figure of 5.5 dB, a gain of 18 +/- 1.5 dB from 50 to 1000 Mhz
and and a maximum output of 55 dBmV, is followed by a 4-way splitter.
Previously, using a Winegard AC-4990 preamplifier the listed antenna and
distribution amplifier, there were 6 truly watchable stations out of 22
detectable. Considering that the Channel Plus distribution amplifier
contributes enough noise to increase the effective noise figure to
approximately 1.3 dB, also considering cross modulation distortion in the
Channel Plus amplifier combined with selectivity limitations of the tv
tuners, the performance is impressive. Thank you.
It's a great preamp. I'm very happy with my purchase. It requires
front-end filtering to perform it's best, at least in my situation. I use the
uhf port of a uhf/vhf diplexer in-line before the input.
It has made a moderate but very significant improvement in my UHF
reception compared to a Channel Master 7777 which I was using before.
