Heathkit KW Dummy Load

(RF) CANTENNA
Originally a 50 ohm, full gallon load. We have no 50 ohm units left, only 70-90 ohm.

Resistor submerged in oil. We have dozens of these beauties that came from Scientific Radio that had been used around their plant. All are used and missing the little cover over the output box on top. To ship (surface only) we remove the lid and place it on a brand new paint can, with packing on the inside for shock protection. We then take the new lid and put it on the Cantenna (with shipping clips), to seal the non-pcb oil in. Now the two cans are ready for transport. Sounds simple eh? Limited quantities available.
