```Hi Dave, ``````This sounds interesting. Are you able to model the "gain" of the loop against a 350ft inverted L fed against a 350ft counterpoise? Same amount of wire but not joined up... ``````I assume your 350ft is the length of the horizontal section? In other words: the inverted L that would fit on my land, assuming I cut down all the trees? :( The length of the vertical portion is all-important at LF since the signal is nearly 100% vertically polarized. Assuming 50ft, the loop could beat the inverted L by at least 10db. I'm basing this on the basic 50ft monopole (with long top 'capacitor') beating the 50/50 loop by the, pretty much accepted, 6db. Then I'm adding 16 db to the loop for the stretched ```horizontal dimension. ```(BTW: I'm not too keen on computer modeling for basic antenna comparisons. My feeling is that good intuitive thinking is often lost) Modeling is great ```for the +/- 1db details. ```I just remember the great fashion of using loops on 160 years ago, ``````Oh, jeez, I first thought you were talking about loops 160 years ago! You Brits aren't THAT far ahead of us! :) ``````these were in small gardens and were about 60ft long and 25 - 30ft high, ``````small but ``````still better in terms of wavelength than what you're proposing. These never ``````seemed to work any ``````better than the equivalent inverted L. ``````Most likely 100% true. LF is a bit different. Because of the very strong dependency on the complete system Q (ground loss, coil loss, and yes - tree loss) the loop can come out the winner, particularly if your lot is a forest of trees like mine. In which case, I just planted a wire or two over the ```tops of them, and now, enjoy their presence! ```Bill A ********************************************************************* This footnote confirms that this e-mail message has been scanned for ```the presence of known computer viruses by the MessageLabs Virus Control Centre.
