## Do they still sell em ? I believe the last time I looked at both Birds
and Coaxial dynamics site, I could not
find the .450 to 2.5 mhz slugS. Back in the day, like 1975, they were
used for AM broadcast, but average power only.
## A scope across a T connector on a 50 ohm dummy load would also work,
provide the scope was calibrated.
## My array solutions Powermaster 20 kw coupler works from 500 khz to 30
mhz. Apparently it works quite well for
AM broadcast purposes. The AS 10 kw coupler works from 1.8 to 60 mhz... and
ditto with the AS 3 kw coupler, same deal,
1.8 to 60 mhz.
