KW dummy load lets you
tune up fast! Extends life of
finals! Run 1 KW CW or 2 KW PEP for 10
minutes. Run 1/2 KW CW or 1 KW PEP for
20 minutes. Run continuous duty with 200
Watts CW or 400 Watts PEP. Complete with
derating curve. Quality 50 Ohm non-inductive
resistor. Use transformer oil (not included).
Low VSWR to 400 MHz. Under 1.2:1 to 30 MHz. 1.5:1 for 30-300
MHz. 2:1 for 300-400 MHz. Ideal for testing both HF and VHF rigs.
Has SO-239 connector and vented for safety. Removable vent cap.

PM-30 and PM-30UV can both simultaneously measure
and display forward power, reflected power and SWR in the fre-
quency range on their dual movement meter system.
Accuracy of the readings is assured because these SWR/Power
Meters feature a true shielded directional coupler.
The backlit meter can also display either peak or average power
readings. Optional 12 VDC adaptor, AC-12 . . . $12.95.
First rate construction includes scratch-proof Lexan front panel.
Measures a compact 5.3x5.75x3.5 in. SO-239 Connectors.
Other Models Available:
PM-30UVN, $89.95. Has N connectors. Covers 100-500 MHz.
