John,
Your idea sounds great for an RF ground system for your radios, however, it
will now leave you radios as a ground path from the house, power lines,
phone etc., to the great new ground. Be sure to disconnect all equipment
from the ground and antennas when not is use.

Daron,
I have never seen anything the was 1 inch on one side and 1/2 inch on the
other. I have gotten angle iron both
unfinished and galvanized at the hardware store. They have some without
holes but only about 1/2 or 3/4 inch to each side. You could drill your own
holes where needed. They
Daron, I guess I didn't know exactly what you wanted to do. Are you trying
to stack the radios?
I went to a CB store and then had lots of brackets and hump mounts. I like
the hump mount because it had little teeth that hold the base on the carpet
without moving, and had a built in 5 inch
Darin, get two ten foot sections of used tower sections at a swap. Made for
your project. Strong, light and you can guy them for extra safety. They

Look for an antenna that is not in use. Sometimes
you can get them for taking them down. Be careful, some are
dangerous.

I guess that the Repeater Builder list was so overwhelmed with Mitrek
stuff
that it was inevitable that another list would be needed.
I'm thinking of starting a list for users of 1/4 wave stainless steel
Hi Sandeep,
I have made a 3 element quad for 2 meters. I used
3/4 inch PVC (stronger then 1/2 inch) for the mast and got two of those
fiberglass flag poles that you put on bicycles to use as the spreaders.
Just drilled apposing holes to hold the spreaders and used epoxy to secure
them. I
Budd, two fuses at the battery will pervert a car/truck fire if the ground
wire comes in contact with hot wire of if the hot wire comes in contact with

Spray the items with WD-40. Re-assemble them and then use an aerosol
battery terminal spray or brush on a waterproof type grease being sure to

Hi,
Our group has acquired a Johnson 440 MHz repeater that they
would like to convert to the Han Band.
There is very little data available on the web for Johnsons.
My question is, what do we have? There is a list of numbers inside the cabinet that probably
