[TowerTalk] KLM Preamp Question

[Mike Ryan]

I have an old ( O L D ) Mirage/KLM 2mtr preamp on my tower that required 12v sent up the coax to power the unit.  This is a flat black aluminum enclosure/box that attached vertically to the mast with two 'U' clamps and both input and output coax connections exited the bottom of the unit. Does anyone have any documentation on this line of preamps?  I have an identical one around for 440. I want to know the throughput power capability and whether these were required to have sequencers used to protect the device, and if not what is the max power allowed without sequencing or ordinary rf switching?  Any help is appreciated. Thanks...  - Mike, K4CVL
