I really appreciate this video. Since getting my SDR I've been looking for an explanation of the nuts and bolts of making a multi-band antenna for receive only.
Awesome video. Counter poise for those who live in high rise is a great tip. I was always not sure how to make it work on the 18th floor where the antenna wire is mounted!
This answered a lot of questions I had, thank you! A couple quick questions I still have, as silly as they may sound: 1) When you're cutting those CAT wires to length, do the "dead" ends interfere with the signal (i.e. should you slide them out of the insulation?) 2) What's the difference between grounding to a rod stuck in the earth vs. the ground in a grounded outlet? (I live on the 2nd floor in an HOA + I've also never seen anyone suggest using the ground in an outlet, so there must be a good reason.) 3) When you say "just one wire," referring to the "hot" wire in the core of the run, is this connected to all of the different lengths of CAT wire in the antenna at the same time, or do you have to change the length of the connection based on what frequency you're trying to receive?
