Hi kids
I'm tuning up a T1504A, which has the 430 - 470 cable set on it. Everything
looks good, except for one cavity - one of the lowpass/hi reject ones. I
can't seem to get a very good null on it, regardless of the loop position.
As a matter of fact, the reject seems to be "getting better" when
Does anyone have data on a Ferritronics PC17 tone board? (at least I think
that this is a tone board)

The bottom and top elements are 1/4 wave in coax. The quarter wave stub and
top radiating
element measure a quarter wave in air. The quarter wave stub, which is just
a piece of solid wire,
connects from the bottom of the lower quarter wave coaxial element (shield)
to the
shield of the 50 ohm fee
Darin,
You may wish to consider one of the aluminum light poles used by the

I am building a repeater with two TK840's. Where can I get a case so I can
put a power supply , the two radios, mobile duplxer, and the controller in
it so I may make it portable. Also, is there a case front to adapt the 7.1"
power supply to the 5.6" kewood radios.
Thank you very much.

Looking for CB Universal mounting brackets.

Radio Shack quit stocking them. Do you know of a site?
I want to mount radio control heads at the museum.

Hi Joe
Using hobby brass as you have .
I have not tried the 1/4 wave stub as of yet.Read
Kevins article-before.
All these designs seem to backed up for a VSWR and
that is why my question-low imp feed with first
element 1/4 or first element 1/2 wave.
Thanks Brad

I never said to use a Tx to put 500kW into a Rx. But may be running
nearby on a dummy load...

How many elements in your antenna? I found at least 8 elements are needed
before
the SWR is low. I used a 1/4 wave stub instead of the open balun seen on
some designs and hobby brass to construct the elements. I found brass
easier to
use than coax for UHF. Check out Kevin's article. It's probabl
