From Dave G3YMC Further to the discussion on loop inductance and various related matters, a couple of weeks ago Mike Underhill G3LHZ gave a talk at our Bracknell Amateur Radio Club on loops. Some of
Hi, Rik and Group. So far I haven' found any formula for rectangular loops, unfortunately this is the most common shape for big transmitting loops. I have derived the formula for rectangular loop. It
Dear LF group, In Rik's formulae, if you make W in m equal d in mm, the formulae reduce to L=1.1W, give or take a few percent,depending on shape - close to RA9MB's formula L=W for a single turn. I ha
One more thing to mention : RA9MB's formula L = D*N^2 becomes a very very simple L = D for a single turn loop (L = inductance in uH, D = loop diameter in m, N = turns). Although it cannot be used for
Hello group, thanks to all who replied to my request, either direct or via the reflector. The result is a nice collection of formulas, both for round as for square single turn loops (3 formulas for r
