Please though, for the love of the spectrum, connect hackrf -> bandpass -> amplifier -> antenna and DONT Forget the Bandpass filter. I don't know of any offhand but that info should get you started in the right direction. I believe the hackrf output is around 25mW so you need an amplifier with a transducer gain of at least 10dB (for matched 50 ohm input and output), designed for VHF (146 MHz), and that does at least 250mW for a 25mW input drive power. Once you have a bandpass filter you need to look for an amplifier with a power output similar to that of a common ham radio HT (.25 to 5 watts) and a drive near the output of the hackrf. Google for one and order the $20 one for 2M from. Assuming you are a ham radio operator licensed for that band we should all be happy to help.īefore you consider an amplifier (which you will need for this almost certainly since 10dB (25mW to 250mW the lowest power output on most HTs) is a HUGE difference despite what others might say here) you are going to need a bandpass filter since hackrf is NOT part 97e emissions compliant (lots of harmonic spurs). Wow these other comments are garbage and give OP no credit at all.
