Can anyone recommend an antenna for a repeater setup on a duplexer?
Frequency is on the VHF 169.0000 / 174.0000 range.
Thanks,

Actually, this isn't always the case. Remember, an antenna for a repeater application runs full duplex if using a duplexer. Which means you need to recieve thru the antenna while applying RF power at the same time. A really cheap antenna will not do the job. It will create so much noise from loose joints and solder connections etc, that you will want to scrap the project. You just can't throw " any ol' antenna" on a repeater, if you want it to work as it should. More details would be helpful.There's nothing really special antenna wise for a repeater so anything that works well on the frequency of operation will work well. One caveat to that is that you may wish to have a high quality antenna on your repeater..
For around $900.00 they better be. Talk about sticker shock but as the saying goes you get what you pay for. If your antenna will be in an area that is not easy to access or have a failure at the worst possible time, then by all means spend the money!.DB224-B
These are hard to beat. They have various freq ranges available from Ham on up to 174. Their UHF version is equally as good. I've installed several.
While this is true, the same thing can be said about the repeater itself. Ideally, you should use a good, commercial grade repeater, but folks are always posting about building a repeater using two low end radios, including two cheap Chinese handhelds. If you want a quality repeater, use quality components combined properly. If you want a junk repeater, use junk components. You'll end up with only as good as you put into it.Actually, this isn't always the case. Remember, an antenna for a repeater application runs full duplex if using a duplexer.
