Instead of buying an antenna tuner, is it possible to build one myself.
Nothing fancy, but a rotary switch and some ?capacitors?. Thanks for the
advice.
I prefer pi-net tuners - two variable caps to ground and a variable
coil in series in the middle. Easy to build and is a low-pass filter
to boot.

Hi Cecil
Hi "Matthew&Wendy"
I prefer resonant antennas and transmission lines that match them.
You just can't beat a resonant antenna for radiation.
Tuners squander AT BEST 1 or 2 db.
At WORST (as Cecil has posted here regarding "shootouts") 10 db.
So build your antenna resonant, match it, and don't bother with a tuner.
If impedance transformation is necessary, use a transformer;
That's why they're called transformers.
That's what they're for.
Just my 2 cents.

Wire antennas are CHEAP.
