"Since no coils are used in this form of loading (a zig-zag in the
radiator length), linear loading cam be used with almost no loss."

Best regards, Richard Harrison, KB5WZI




I would speculate that the opinion that coils are more lossy is from the
practice of using relatively thin wires for coils vs. heavier tubing or wire
for the linear loading.
With linear loading, depending on its mounting or folding, it will do some RF
cancellations and interacting with radiator, while coils are much "cleaner" in
this respect.
Again, W6?? drastically improved loaded 3 el. KLM 80m beam (efficiency,
pattern) by replacing linear loading with coils.
So maybe time to be more specific about what kind of coils vs. lin. loading.
Another subject for real life tests and measurements.

Yuri, K3BU
