Home Made UHF 50 Ohm Dummy Load
Hi,
I wish to make a 25 watt (short duty) 50 ohm dummy load for UHF 440Mhz band. I have a UHF SWR meter and I have made dummy loads before, but they are of little use at UHF frequencies due to internal capacitances in the resistors. The only good dummy load I made that works very well at UHF is a 2 W 50 ohm straight carbon resistor solder on the inside of a PL259 connector. I can use this as a 10W (short duty) dummy load as long as I make a brief transmission. I thought about putting five 2 watt 10 ohm straight carbon resistors in series inside a copper tube which is soldered to the back of a PL259 connector. What are your thoughts about this idea? Thanks in advance, Brad Before you type your password, credit card number, etc., be sure there is no active key logger (spyware) in your PC. |
