I have been constantly annoyed by the poor reception
that these Omni directional mast
mounted antennas . So I thought i would research
this a little and possibly improve it for myself.
When I started I had a Shakespeare 2025 with the below deck
gain adjuster . This part gave up right way and rendered the antenna
useless. Apperently this gain adjustment is just a power injector that sends power up to the antenna
via the coax cable to a small amplifier built inside the antenna housing. The housing opens easily.
First I had to replace that with a much better one , not sure what the specs are on that small amp but it looks very cheap
I put in a Kitz , KT 200 , from Ultimate TV Antenna Signal Booster, TV Amplifier, HDTV Booster! Guaranteed!
these little units get great reviews
on the AV forums
, they are ultra quiet . The more noise
you add the more drop outs you get . This thing fits right inside the housing , you have to solder on a impedance matching trnasformer
to were the old amp came off and relocated the cable inlets, but all very simple , took about an hour.
Next thing, if you have RG59 coax cable , tear it aLL OUT ! Put in RG6 , much lees DB loss in the wire especially for longer runs like what us sailors have to use
The results , Wow what a difference 41 channels locked on ! compared to 25 before that would always drop out half way through a show .
So I think it was a great upgrade .
