Re: Availability of Mag Loop and other stuff...


A SWR of 1:1 is easy with a dummy load but as a radiator its efficiency is very poor.
Some antennas can be matched to a good SWR and still be poor radiators.

SWR is not a measure of antenna effectiveness or efficiency its a statement of
how well the load is matched to the source.

So where does the energy go, mostly heat.  the comment I hear often, I I can
measure no warming, completely missing that all that copper or aluminum
will radiate heat well.
