Remember, these are for SHORT TERM use. You do not use them at the top of it's rated DC power while doing TX or RX for long periods (multiple hours), They will get hot, and that will impact your signal.

Non proprio economico ma funziona!

Performs as stated. Well built. Very happy with it.

I use this to isolate my LNA from the rest of the electronics. After nearly a year I have had no problems.
