1. [TowerTalk] Dummy Load power resistors...questions! (score: 1): Author: <n0tt1@juno.com>; Date: Sun, 28 Jun 2020 18:43:43 +0000; Hello everyone, I recently aquired a "commercial" dummy load that I'm sure will handle more than 2kw. There are 12, 600-Ohm resistors in parallel that measure 50-Ohms with a Ohmmeter. The resistors l; /archives//html/Towertalk/2020-06/msg00226.html (6,884 bytes)

Definately non-inductive for this application, but the power rating is, I don't know. I know it was used at a 5KW AM radio station for some testing.
