Right now, my indoor antenna couples to a catv amp. From the amp, about 15 feet of rg6 is my pc desk. At the desk, the one line gets split between a bcd436, an airspy mini. and 2 cheap china dongles. And I get good distance for an indoor antenna. And I receive most of what I want to hear. I am into it all. Police and fire, fed, mil air, civ air, maritime, trunked dmr with the dongles. Unitrunker weather sat.etc
I want to try an lna that's meant for radio and not the catv amp I have been using. Tho it has done the trick, it's time for something new.
I am torn between lna4all (with bias t) and janilab (with adjustable gain).
I know my airspy should power a bias t lna, but can any harm come to either the 436 or the china dongles if the bias t was enabled on the same run of coax? I am in an apartment and between their rules, and my wife's rules, I can only get away with so much.
I like the lna4all with bias t because when I travel, I go light. And a dongle that can power an lna means less stuff to pack. Plus, here at home it would mean 1 less wall wart sucking up juice all day. But I also like the janilab because its gain can be adjusted by turning the pot. I think I read lna4all gain can be raised or lowered by changing the voltage if not running bias t..
But I guess the main question is, if I enable the bias t on the airspy mini, can anything connected to the coax get fried? Like can the power screw up the china dongles or the 436?
Open to any advice, opinions and comments.
Thanks
