1. [TowerTalk] Sources of Coax Relays (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Wed, 11 Jul 2012 20:58:30 -0700; I'm looking for good quality coax relays for use at the 1,5kW level. Some will be used only on 160M, most will be used on the HF bands. I may have a use for a few at the 200W level on 2M. Some will b; /archives//html/Towertalk/2012-07/msg00101.html (7,114 bytes)

I assume you're looking for something reasonably inexpensive, that is, you're looking to repurpose a conventional DC-60Hz kind of power relay to RF.

Available in a 24v version as well. Has nice short contacts keeping the L low.

But for those of us who (like me) are new, can you expand a little, and, particularly, give a couple of links?

Thanks. Steve K8JQ _______________________________________________; /archives//html/Towertalk/2012-07/msg00106.html (12,397 bytes)

There was a multi-rig switching unit featured in QST/QEX in the last year which had the relays mounted there.

Re: [TowerTalk] Sources of Coax Relays (score: 1): Author: Jim Lux <jimlux@earthlink.net>; Date: Thu, 12 Jul 2012 20:43:25 -0700; The challenge is that relays that worked 15 years ago may not be available today, or even if available, work today.

They also have to provide isolation at that power and frequency when used in remote antenna switches. Even more so when t; /archives//html/Towertalk/2012-07/msg00122.html (10,444 bytes)

If the switch is based on two relays per antenna and unused antennas "float" relay capacitance will cause coupling problems.
