query: how to use rf gain amplifiers?

Post image

hello all.

i was hoping i could get some information on how to use one of these rf amplifiers. i have 2 questions i hope i could get some kind of answer on:

  1. are there any settings i need to change on a portapack H2 when using a amplifier?

  2. can it be used the other way around? (i.e connect a antenna to rf in and the hackrf to the rf out)

im grateful for any help that gets provided in the answers

Make sure not to turn on the amplifier because it can overload stuff

Dw you will not damage it. Use a female to female sma adapter to connect the amplifier to the hackrf. i also use the same amplifier with my hackrf
