1. [TowerTalk] Relay Recommendations (score: 1): Author: "Matt" <maflukey@gmail.com>; Date: Fri, 9 May 2014 16:41:13 -0500; I would appreciate recommendations for general purpose SPDT relays that can be used reliably for RF antenna switching duty - it is not a hot switching application. I am aware that the DC & 60hz AC ra; /archives//html/Towertalk/2014-05/msg00178.html (6,690 bytes)
2. Re: [TowerTalk] Relay Recommendations (score: 1): Author: Grant Saviers <grants2@pacbell.net>; Date: Fri, 09 May 2014 16:37:39 -0700; I'm trying out some of these in a QRO remote antenna switching application SPST, so far so good. What is different in the (clever) design is the coil isolation is 5KV. The contacts are rated for enou; /archives//html/Towertalk/2014-05/msg00182.html (8,979 bytes)

Re: [TowerTalk] Relay Recommendations (score: 1): Author: <john@kk9a.com>; Date: Fri, 9 May 2014 19:39:34 -0400; There are so many inexpensive relays that will work for RF antenna switching, assuming that you don't have excess voltage from unmatched antennas.

Re: [TowerTalk] Relay Recommendations (score: 1): Author: Mike <k4gmh@arrl.net>; Date: Fri, 9 May 2014 20:26:10 -0400; Hello Matt, I've been using Tyco RTB14012F SPDT relays (12 V DC ~30 ma. nominal op. current) in all my remote antenna switching arrangements. Run 1500 Watts RTTY, SO2R. All the relays are controlled; /archives//html/Towertalk/2014-05/msg00184.html (8,433 bytes)

7. [TowerTalk] Relay Recommendations (score: 1): Author: "Jim Thomson" <jim.thom@telus.net>; Date: Sun, 11 May 2014 18:17:09 -0700; How about isolation"? Multi op, or more like SO2R. Multi antennas at QRO, or just a lot of remote switching? The 6-Pack is for SO2R and just runs open frame relays. For that kind of service most open; /archives//html/Towertalk/2014-05/msg00226.html (9,545 bytes)
