The cable and plug alone are worth more than that. An omni isn't the best for long distances, I'm told, but I can't argue with success. I'm definitely getting one of those for experiments. Bruce

Haha. Didn't have the connectors and none in local shops. Didn't want to wait for delivery. Also, I was trying to minimize the number of reflections by using as few connectors as possible. But with using the wrong impedance cable and all, the connectors might have helped as much as hurt. Anyway, the board had nice big solder pins and I figured "What could go wrong?". My bad. I've done some more testing. I don't see any difference by using one can instead of two. That is, shortening the length to 6 inches. Easier to aim. Maybe there are differences on the order of a couple of dB that I don't see in my ramshackle setup.

The exposed inner conductor of the probe should be 1.21". -- --- Clarence A Dold - Hidden Valley (Lake County) CA USA 38.8,-122.5 |
