100Watt Dummy Load (20xResistors Array)
The dummy Load uses 20 1Kilo-Ohm 3 watt non-inductive resistors in parallel to achieve 50 Ohms over a wide frequency range. It is submerged in oil to allow somewhat extended operation during tuning or repair procedures. The advantages are: (1) It's cheap, only 2 PCB's act as the connection (2) It provides a very pure 50 Ohm resistance load through 30 MHz and beyond, (3) You can easily add power measurement and rig testing capability.(PCB has a place to install on board a diode and a capacitor ) This one is conservatively designed for rigs that have power output levels up to 100 watt. I built it into a one-quart paint can, readily available at Ace Hardware for about 89 cents. Supplied pcbs can be easily assembled with readily available resistors carbon film .. What is Included 2 x PCB'S ( No Resistors Included )
This dummy load uses twenty 1 kΩ, 3W non-inductive resistors in parallel to achieve a precise 50 Ω load over a wide frequency range. Submerged in oil, it allows extended operation during tuning or repair procedures.
Advantages:
(1) Cheap – only two PCBs act as the connection.
(2) Very pure 50 Ω resistance from DC through 30 MHz and beyond.
(3) Easy power measurement & rig testing – PCB includes pads for adding a diode and capacitor.
Conservatively designed for rigs up to 100 watts. I built mine into a one-quart paint can (about 89¢ at Ace Hardware).
Supplied PCBs assemble easily with readily available carbon film resistors.
What's Included:
2 x PCBs (resistors not included)
