Using sports oval light poles as an antenna on 160 metres
A great thing about this approach is there is no direct electrical connection to the pole. Thus you don't have to shinny up the pole and hope there is an electrical
connection to it. Instead you use a coupling loop supported on a telescoping pole against the pole. I'm not sure how much loss there is but most peoples 160 metre
antennas have some degree of loss. The results seem to indicate that this one is better than most, especially for ground wave contacts (I haven't tried it for DX yet).
Introduction and 160 metre tests
These videos describe the coupling loop. I demonstrate the antenna on a local 160m AM net.
Use on 80m
I suppose you can say it worked on 80m but it's probably not worth the trouble for most contacts, especially over short and medium distances. This is likely
Driving a crystal set
Getting back to medium frequencies and ground wave propagation, the pole did well when driving a crystal set. Increased capacitor values in the coupling box
Calculating the height of a light pole
It's easy, provided the sun is out and you're in an open area. This video shows you how.
