diy full wave 11 meter loop antenna question

[HomerBB]

I know this is an old thread, but for future reference, and to uncomplicate the transformation of an 11 meter full wave loop to a 50 Ohm feedline, I simply purchase a ready made 6' long 75 ohm A/V cable and two F connector to HF adaptors and put it at the antenna end of the feedline. To fine tune the loop I start longish on the length and adjust it down to my best match, usually 1.0:1.

Perhaps because CBers only use a small slice of the RF spectrum with mono-band antennas,................................ and seem to think that the VSWR MUST be 1.0:1.

Modern CB and Exports are using non-rf mosfets that are designed for motor control or voltage regulation. If the swr goes above 1.5:1 they start poping like fast blow fuses!
