2M/70CM Repeater

[email protected]
 

I am putting up a 440 repeater with the 2M (147.300 Brown Co., Indiana) repeater that is already in operation. The 440mc machine will use the same antenna that is going up soon (a GP-9). What is the best way to come off the hardline to get to both sets of cavities? I was thinking of a 3/4 wave section of coax out of a "T" connector to each cavity set. If this is used how critical is the length? HELLLLLLP!!!!!

I use the Larsen diplexor. It's a heavy duty model that can take up to 200w.
Plus it is a sealed unit. I have not had any problems with desense. Good luck
with it. 73, Gary

I'll tell what we are doing at one of our sites... depending on your power
output. We are using an actual COMET Tri-Plexer for our 2Meter /
220packet / 440link repeater site. And never have any desense or problems
with them getting into each other. Maybe that'll work for ya ??

Peter,

Get a Comet or Diamond dual band mobile duplexer (diplexer) they will work fine for this.
I have a few repeaters that use dual and tri band antennas. Some are configured with one port as a repeater and one port simplex, some are two repeaters and a digi, some are all ports going to repeaters.

Just get one with enough power handling capability.

Do they make a duplexor that will handle 100 watts?

well for what it is worth i am now using the diamond due to it has a removable
cover on the back and allows repair if needed like on the center conductors of
the N or SO-239 connectors thanks to the cover i did not have to purchase a new
diplexer just fixed to solder joints and it is like new
