Greetings. I'm the trustee of our local club's 2m repeater. It's NE of the
big town of Joplin, MO. (147.210) What I want to find out, I'm going to ask
our club to buy a new 224e antenna (assuming that this is the correct version
needed for T147.210 R147.810), and arrange the elements on the north
What do you do when you want to install a small UHF linking repeater on
a 4-story building that has no lightning protection on its' roof? (this is to
link an ambulance at a hospital to its' base repeater 40 miles away)
From what I've heard, it may not be a good idea to hook it to the HVAC,

Howdy! We're getting ready to move a repeater to a taller, more robust home.
We have access to a run of CableWave 1 5/8" Heliax. Here's our question:
Will an Andrew H7PNF work with CableWave HCC158-50J170 Heliax?
If not, what Andrew connector will work with CableWave HCC158-50J170 Heliax?

Sorry, Ron, I disagree with the relay idea. If it's critical that the radio
power supply be up all the time, then run it in the emergency circuits, which
ARE active all the time. Our main ambulance radio and our maintenance repeater
are on emergency power, as I specificied and coordinated the
