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

I'm thinking of buying a Kaito KA-31 shortwave active loop antenna but before I do I thought I'd ask if anyone has any experience with this antenna and if so, would you be good enough to share your

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

Actually Patrick, Just shorting together the bottom points of the tube where it meets the base, would cause it to be a shorted turn, which would then totally disable the antenna, whether or not there

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

I've been thinking about this myself. Those disks are mostly aluminum so they should work. John Nelson KE5FRY --- antloopernew <dgmfield@...> wrote:

Did you try to ground both (and at the same time) left and right side of the Al tube, close to the plastic case, to the ground of the coax? Otherwise, grounding as you discribed has indeed little or

Hi Rob, inside the tube, the wires are connected to these srews with AMP clamps (you know, you press them on a cable and they have a little U-shape or O-shape to put a screw through. Patrick. Rob

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

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

John, At the bottom of the Wellbrook ALA-1530 information page, there is a calibration chart which show the Aantenna factor vs frequency. It indicates that the antenna factor is roughly 8 over most of

Hey Everyone; Newbie/first poster here. So 'hello'. Been following the Wellbrook saga with great interest. Warning: While not a hands-on expert, I have read enough about active loops to be concerned

A new amplified loop design has been posted by Dallas Lankford on kongsfjord.no - inspired by postings by John KC0G on this group. Bob
