DIY Short Vertical Wire Loaded Antenna: Using 20 Ohm Resister to Widen Q

Great work so far! It's reasonable to add a resistor to increase the bandwidth - if you're not using a tuner, so you need it to work in various situations and across the band, then it's your only real ...

Link budget validation for a UHF satellite ground station

There could be many things going wrong so this is a slightly rambling answer, a primer on low noise ground stations. I suggest reading about amateur EME stations, there is more published there than on ...

How is it possible for a halfwave dipole antenna to be resonant?

This is a dipole antenna with a feedpoint, to borrow your picture. Your diagram shows a dipole with a transmission line feeding it, which is a more complex system. In your exact case the transmission ...
