I agree, but I fugure that is why they invented electrical tape... or maybe use duct tape... or whatever works. Photographers gaffers tape is a good choice because it comes off without leaving

Re: Interesting page on RF noise, H versus V and why loops may not be the answer
But that discussion misses the point that the high impedance rfi you are avoiding with a shielded loop comes from nearby, in the near field, while the signal you are receiving is from far away. If the

Re: Wellbrook grounding test results
Hi Nigel, Well, just put it down to intellectual curiosity. I want to completely understand how the loop works. Having the loop be the antenna is certainly one answer but that's not what I seem to see

I didn't try grounding both side of the aluminum tude but I will in the next day or so and let you know. I'll have to disassemble more to see if there are any "amp clamps" in the tube. Rob wrote: side

Well, I went out and both grounded the loop to the shell of the BNC connector and also tried grounding it to a ground rod I had put in previously. The results were......... No change. I had my G313E

Re: Wellbrook construction
If you actually took a look at a Wellbrook, you would see that the design has the coax shield as a common gnd point. Unless the aluminim ring is "hot" with respect to common, it should not cause any
