Dummy Load

A dummy-load is a useful item to have when you need to test a transmitter without radiating a signal.  This design uses a number of resistors dipped in oil to form a 50-ohm load that can take 108-watts "as is".  The addition of oil as a coolant allows the resistors to handle around twice their rated power for short periods, typically on a 1:1 On/Off ratio.

For a little more than a 30-watt oversize PL259, you can have a robust unit that will take more than 100w all day long.

Each unit is individually tested and a calibration sticker attached.

• 1.8-150MHz @ 100-watt continuous
• Uses 36x 3W 1k8 Resistors
• N-Type or SO239 connector
• Size: tbc
• Weight: tbc

Available towards the end of January and the first batch of 10 will be at a lower price than shown above.
