Should they be connected:
c) Between the low pass filter and the antenna?

You'd be quite lucky to have an installation where there
was no ATU after the LPF because of an extraordinarily
well matched antenna, butÂ* if you were so equipped then
the SWR bridge could be used as an emergency indication
that something was at fault on the feeder or the antenna
itself, otherwise a pretty pointless installation.

e) At the antenna output socket?

Usually between the TX and the ATU; ie the TX antenna output
socket and not that of the ATU.

We all know that ATU is a misnomer because it does not tune the
antenna but acts as an impedance transformer. The RSGB seems
to prefer the name ASchew. (which seems medically undesirableÂ* :-)Â* )




Would you consider the description Impedance Matcher rather than
Impedance Transformer please ?
