This is my 434MHz slim-jim antenna that I tape to the top of my 10m fibreglass telescopic pole for High Altitude Balloon tracking. It is made out of 300-ohm feeder and is fed directly with 50-ohm coax. Due to the high frequency and the fact that I don't transmit on it, a choke balun is not currently used. My RTL-SDR Tv Dongle is included for scale.
