yes we mostly one TX antenna and one RX antenna with pre amp on it and notch filter for 465 to 469.9

Their combining equipment does not take up two footprints in the tower shack! The combiner that was just installed in my building is over 43 inches wide! The owner of the tower will thank you, I would. I will also warn you, when you have to duplex, combine and multicouple to get two systems on one antenna you are looking at a lot of loss, it would be better to install two antennas. With two antennas you would not be affecting the host radio system, in fact you may help his range a bit depending on how much loss is in his duplexer. Just my 2 cents, Paul ------------------------------------------------------------------------------ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Maire-Radios Sent: Wednesday, February 20, 2008 5:05 PM To: [email protected] Subject: Re: [Repeater-Builder] Two Repeaters, One Antenna give TX RX a call and they can fix you up.

John ----- Original Message ----- From: Cort Buffington To: [email protected] Sent: Wednesday, February 20, 2008 2:38 PM Subject: [Repeater-Builder] Two Repeaters, One Antenna Guys, I've found a site for my most recent Ham repeater project. Nice farm tower on a hill, clean of RF colo, etc. The farm repeater is a 463.xxx + machine and I'm on 444.825. It is set up with nice hardline and a 16 bay folded dipole antenna (not sure the mfg., but he thinks it's DB). Anyway, assuming that thing has useable SWR on my TX frequency (I've had that happen before, not holding my breath), does anyone have any ideas about the viability of running both repeaters on the same antenna but connecting the duplexer outputs together in to the common feedline? I've done no math, and not a lot of thinking, but is this one of those times when I might run odd multiples of 1/4 wave coax to a T at the hardline or something? Both repeaters have BpBr duplexers and both have isolators on their outputs. 73 DE N0MJS -- Cort Buffington H: +1-785-838-3034 M: +1-785-865-7206 REMEMBER - You can find it on ebaY No virus found in this incoming message.
