For several years I've been looking for a way to use a single
receiving antenna to feed several radios at once.
I've looked at the manuals for TMC equipment. Nice if you like
a rack mount full of vacuum tubes. Although they also made a
solid state version.
There seems to be a "black hole" on the internets about broad
band amplifiers that will cover .5 MHz to 30 MHz.
While browsing some older editions of the ARRL magazine QST, I
ran across a clever distribution amplifier, but the IC used is
no longer available.
A bit of research on the Maxim IC site and presto, the 4022
quad op amp. Pretty much a DC to 300 MHz quad amp with +6 dB
of gain running off + and - 5 volt supplies.
Being located in Ranger Texas, I don't have to worry about
having things like KNX 1070 AM or several FM stations within
overloading range of the amplifier.
Now off to gather supplies for a nice flat top antenna array
for the roof of the shop.
