My 7MHz magloop VSWR only dips to 4:1. The resonant point is not very sharp (maybe 50KHz wide), but the RX noise seems to be peaking well at this frequency. My main loop is 1m dia, capacitively tuned using an approx 1 metre length of open ended RG58 coax, and the feed loop is 1 fifth of this diameter which I am feeding with 50 ohm coax.

It does seem to get out on Tx but I am having to use an ATU to match.

Any of you magloop experts have any idea why I can't get a lower VSWR?
