I need a little advice on using antenna analyzers to tune topband antennas. As they are pretty long I assume they build up some static that might hurt an instrument connected. Am I right? I just boug
Thanks to all answering me on this topic, got quite a few replies off list! The consensus seems to be that there is no need to worry about static build up when using the analyser on large antennas. M
The consensus seems to be that there is no need to worry about static build up when using the analyser on large antennas. >> Having been involved in the design of antenna analyzers I strongly disagre
A little off the subject, but I have an extensive earth grounding system using neighbours fences, and earth spkes every 20 to 40 ft apart. This extends 1.5 miles to the south and about 1/4 miles west
I agree totally. I spent most of my career in discrete semiconductors (including schottky diodes), first as a product engineer and then as a manager at various levels. The metal-to-semiconductor cont
Tom: Is there anything on your web site that discusses how one could run a check on the MFJ-259B and feel comfortable that their analyzer diodes are functioning correctly? [preferably a simple check
I agree with Tom When I was working on my vertical array, I had my my HP network analyzer attached to an antenna, a few non-threatening clouds came up, I heard a little snap, felt a little shock, and
Tod: Get a 51 ohm non inductive resistor and put across the input. It should read 50 ohms and zero reactance or close. Put a known capacitor or inductor value a cross the resistor. Calculate the rea
Dave, thanks for the great idea! I will use a T-connector with a shorted BNC plug when connecting the antenna. And thanks to everyone who contributed to the subject! 73 de Björn /SM0MDG _______
Gary: I should have said, put the capacitor or inductor in series with the 51 ohm resistor. I tried it on my MFL-259B. I used a 150pf silver mica in series with a 51 ohm resistor. At 5, 10 and 20 MH
