A while ago I came up with the idea of building a portable ATV receiver. Important features of this receiver had to be: 1. Large screen with real noise (no fake noise) 2. Of...
I’ve been thinking about setting up a symmetrical antenna system for a while now. That is, Ladder line fed dipole. I did a bit of measuring and was able to stretch 2 x 9m...
