Chris Receiving signals on a piece of wire lying on the ground is totally different to Transmitting a signal over any distance. You are getting into the beverage antenna theory where signals can be r

Hi Mal, Thanks for your comments. However, we need to bear in mind that running two wires out to tent pegs in the ground does more than give you a double Earth connection. They can act as effective a

It would appear what some are using for antennas ie Earth Mode, I am using as a ground system for my Airborne antennas. No wonder maximum tx range is very limited. A more straight forward approach to

Hi Mal, Good point - you don't really worry about antenna efficiency at LF for Rx, but of course you do need to for Tx. I agree with what you're saying. 73, Chris G4OKW -- Dr Chris Trayner School of

But if I understand what you say the antenna is 4m above ground, slopes up at 45 degs, what height ? then down agn to 4m. This is an Elevated antenna, I am still confused because my impression of an
