The AV640 works well on 40 through 6, but it's not designed for 75/80.
Some claim to use them on that band but like "half slopers" YMMV
*greatly*. Even at low power I'd be concerned about the matching network
voltages on 75. I don't remember what mine measured, but I do remember
It's highly reactive and the impedance is way off. OT OH if need be it
wouldn't take me long to check. The meter is only about 5' from the end
of the coax out in the shop.
