[TowerTalk] Testing traps for heating

Hi TTers,
I would like to test some homebrew parallel resonant
traps for heating and breakdown without transmitting
on the air with full legal power and without an elaborate
setup.
The two types of traps I want to test are high inductance
self-resonant types and the "standard" inductor/coax
capacitor type. All are parallel resonant in the 20, 30,
40, 80 meter bands. Of course the 30m trap need not be
tested to 1.5 kw.
I'm thinking I could "feed" the trap-testing setup with
a antenna tuner, with a trap connected in series with a
dummy load in an off-resonant condition.
For a parallel test I was thinking that I could hook the
trap in parallel with another tuned circuit that would
have taps for impedance matching for input/output.
Any suggestions or thoughts on this?
I looked on the web and TT archives and QST/QEX indices
but no luck.
73,
Charlie, N0TT
