1. [TowerTalk] SWR and voltage (score: 1): Author: Steve NR4M <steve@nr4m.com>; Date: Mon, 26 Sep 2016 11:17:48 -0400; Hello all, As I recall, in a 50 ohm system, 1500 watts is about 400 volts and about 6 amps. Could someone give me an approximation of what I could expect at 2:1 and 3:1 SWR? Or, direct me to a formul; /archives//html/Towertalk/2016-09/msg00442.html (7,973 bytes)

Re: [TowerTalk] SWR and voltage (score: 1): Author: Steve Hunt <steve@karinya.net>; Date: Mon, 26 Sep 2016 16:38:43 +0100; Steve, Firstly your figures are out for the 50 Ohm system; the figures are 273.9V and 5.5A Once the SWR is no longer 1:1, there is an infinite range of impedances for any particular SWR, and therefor; /archives//html/Towertalk/2016-09/msg00443.html (9,008 bytes)

Re: [TowerTalk] SWR and voltage (score: 1): Author: Steve Hunt <steve@karinya.net>; Date: Mon, 26 Sep 2016 16:42:48 +0100; Steve, Those were rms figures of course; if you need peak values, multiply by 1.414 Steve G3TXQ Firstly your figures are out for the 50 Ohm system; the figures are 273.9V and 5.5A Once the SWR is no; /archives//html/Towertalk/2016-09/msg00444.html (8,327 bytes)

I should have mentioned that I was looking for a max number. Would hate to have the device conduct while running the 'full boogie'. 73 de Steve, NR4M Firstly yo; /archives//html/Towertalk/2016-09/msg00446.html (9,588 bytes)
5. Re: [TowerTalk] SWR and voltage (score: 1): Author: Richard Solomon <dickw1ksz@gmail.com>; Date: Mon, 26 Sep 2016 08:49:42 -0700; Wouldn't Peak to Peak values be needed ? In which case the multiplier is ~2.8. 73, Dick, W1KSZ _______________________________________________ _______________________________________________ TowerTal; /archives//html/Towertalk/2016-09/msg00448.html (8,905 bytes)

Re: [TowerTalk] SWR and voltage (score: 1): Author: "Gary Schafer" <garyschafer@largeriver.net>; Date: Mon, 26 Sep 2016 12:35:16 -0500; No, there is no such thing as peak to peak except on the scope screen. You want to use peak values to figure the protector voltage. 73 Gary K4FMX _______________________________________________ _____; /archives//html/Towertalk/2016-09/msg00453.html (10,330 bytes)

Re: [TowerTalk] SWR and voltage (score: 1): Author: Dan Maguire via TowerTalk <towertalk@contesting.com>; Date: Mon, 26 Sep 2016 20:51:29 +0000 (UTC); For those folks who like to have pictures to go along with words here are a couple of ways to illustrate the voltage and current (both rms) along a transmission line. For example, at 14 MHz with a lo; /archives//html/Towertalk/2016-09/msg00459.html (9,992 bytes)
