Even at that height, this discussion has not taken into account the polarisation coupling effects that have to be considered at MF. In some parts of the world you won't get good coupling into the ion

Hi Len, Well I'm glad you guys are having fun. I've just returned inside from the shack, having sat through 30 minutes pre-sunrise without hearing a single signal on the band, except for the ZL digi

I have recently erected a 320m Bev at my new remote receive site. This is the first Bev I have used in ZL ( I did have one in ZS), and it is working extremely well. Since I also have an N2PK VNA (vec

To all the Beverage gurus. I have an opportunity to make a 1100 ft 2-wire Bev on a remote site, but the wires will be suspended independently in tree branches. Line impedance will therefore not be un

Does anyone know a short way using EZNEC to show the RDF of a TB antenna? I would have thought that it should be shown on the FF plot somewhere but I don't see it. Seems a pity to go and calculate it

The material permeability can be determined, but you will need to know the effective length of the magnetic path, and the effective cross section area. My guess is that you should be more interested
