Hello everyone,
I'm looking at how to make a dual pol feeder with decent separation for 5-6ghz band, the classic tube with dipoles would be ok, but I dont know how to do sizing/reflector for the outer dipole.
I'm also open to different designs, like cassegrain or exposed dipoles with reflector...
Hello everyone, I'd like to build/assemble a simple 216mhz AM receiver, do you have any suggestion about design/ic/kit where to start from ?
Kind regards,
Giacomo.
Thank you for your suggestion, looks like the perfect solution for me, I also searched for transverters but found nothing, the dealer you linked me has a lot of useful things, if you know any other please PM me :)

Hello everyone,
I'm testing this amplifier and I noticed a lower current drain when I connect the output of it to an antenna instead of the spectrum analyzer/load.
The antenna I'm using is a simple whip / mobile antenna, but it is sold for the frequency I'm using it (433mhz)
Can you please...
