Try a 50 Ohm 200 Watt Resistor! But don't touch it if you feed it with
200 Watts for very long. Hi! Hi!

PS: There is a full schematic and color photos on the web somewhere that
shows how to build a copy of the Heathkit "Cantenna". I will try to find
it. If I do I will post the address.
It is essentially just a bunch of resistors in parallel to obtain a
higher power handling capability at 50 Ohms attached to an SO239 chassis
mount coax connector mounted to the top of a paint can. The paint can is
filled with mineral oil to allow even more power dissipation. The old
Heathkit units were rated at a full Kilowatt.
