I had a situation where I needed to do that at a repeater site in Sioux City, Iowa. We had about 35 watts on the UHF & about 25 watts on the 2 meter, using a Comet tri-band GP-15 ant 4160 diplexer.
It's been operational for about 4 years, working fine. Certainly, mono-band antennas are best. But this replaced a Moto Comm-prod 8DB stick on the UHF & we notice very little difference before/after. ------ Original Message ------ Received: Thu, 25 Nov 2004 09:58:51 AM CST From: "w9mwq" <[EMAIL PROTECTED]> To: [email protected] Subject: [Repeater-Builder] Dual Band Antenna for repeater use > > > I know what this question can lead to, and I know dual band > antenna's are not recommended for use on repeaters, but this is a > short term use, (Winter), need.
