Well, now that it is summer in MI I finally am installing a full new
satellite setup, but the preamps have always confused me and I am
looking for help to get it right once and for all.
All the latest conversation shows I should get ARR or SSB preamps.
My question is two-fold:
1) Which models of each for UHF/VHF? (do I need the mast mount type
so I can put them outside, or can I put them inside a small
weatherproof enclosure)?
More importantly:
2)I am confused by Bias T's, Power Injectors, vs just running 12volts
of a power supply up to the small tripod and connecting it to the
preamps.
From what I can tell I need preamps that sense transmit and receive
since I will be likely transmitting and receiving on such things as
PCSAT on the same freq. So it needs to pick that up remotely on the
coax? So, with that said I would imagine that is the RF Switched
version of the ARR preamps. Then, I am just down to how do I power
them? It seems to me that putting both the UHF and VHF preamp in a
waterproof enclosure and then running 12volt power to them makes
sense, but if I could power them via Coax that would be easier to do
in the setup.
The radio is a TS-2000x if that helps.
I am sorry for the n00b questions, but I really want to get this
right. I have bought the some AMSAT books also to try and help me
understand the preamp setup.
Thanks,
Mike
