i'm testing a 15 mm copper pipe magloop, length presumably 3 m; the coupling loop is a 60 cm perimeter faraday loop; required capacitance for tuning is 8 pf on the 12 metre band and 82 pf on the 30 metre band; like the `operational' magloop, swr 1:1 was much easier to achieve at the lower frequencies; the bandwidth is not as wide on such frequencies as the operational magloop, but it is not as tight as the calculator (aa5tb, at the moment) predicts either (50 khz between -3 db points, using 30 watts)

000057f6 | 2007-10-11T10:33:00Z | magnetic loop antenna | -mt4-

aa5tb says that the bandwidth should be that wide (about 60 khz) for a 1 mm diameter main conductor; i've just tested it and it's true; as the diameter increases, so the bandwidth should decrease; so why does the copper pipe have the same bandwidth? perhaps the connections should be cleaner

the `operational' loop does not transmit very well; that could have something to do with its being hidden at the top of a bay tree, but it's probably mostly due to the coupling loop being so large; when i was unable to get good swr at the top frequency during testing, it seems that i should have made the main loop smaller instead of the coupling loop larger; certainly, i have tried a 2.4 metre perimeter loop in the bedroom this evening and it has given good swr; perhaps i will be able to get it somewhat closer to the 3 metres i had originally intended, but that's not too important; at least i have found a way to make progress; while the operational loop is down for adjustment, i might adjust the capacitor too; the mobile plates could do with a trim, i think, to increase the clearance between their sides and the rods that hold the static plates; i have observed that there might be flashover at maximum capacitance

i tried a few more tricks with the magloop today, before happening to swing the door on which it has been mounted for each testing session; the tuning changed dramatically, and i was left to surmise that the objects on the shelving behind the door could have been responsible for the poor results not just of this loop, but of the redeployment of the original loop and another loop since; i have recalled that, due to the magloop's high sensitivity to metal objects, i carried out my initial testing on the first loop with it mounted on the plastic pole on which it was to be deployed; there is a plastic pole in the back yard; i'll try using it tomorrow; at least my redesign/refurbishment of the capacitor was worthwhile today; i shaved the mobile plates as planned and moved the links between static plates from the sides to the top, reinforcing them with washers; the intention is that the loop ends will now connect by being squeezed beneath the bottom-most static plate, with the same pressure strengthening the inter-plate links
