Convogliare su di un'unica discesa il segnale di due antenne
DIY 2m / 70cm Diplexer for Satellite
Here's a small 2m - 70cm diplexer that is good for up to 10W of power, perfect for working satellites with a HT
HF+VHF/UHF Diplexer
The following Diplexer separates the following bands - HF and 6m on one side = 0 - 52 Mc - 2m and 70cm on the other side
HF/VHF Diplexer
One band I've been wanting to activate is 6 Meters, my first challenge was I didn't want to use a coax switch to flip between HF and VHF
HF VHF receiver diplexer
To enjoy the full range of the receiver, I need to change antenna I decided that I need a HF / VHF receiver diplexer
