ROTFL! You've considered Wellbrook or Cross Country Wireless loops then? Probably 1/10th of the cost of DX Engineering. Never heard of either company, but what they're offering is what I had in mind. ISTR coming across such a published design at one time or another which is what triggered my OP. I had in mind two such antennae mounted orthogonally, powered via the coax cable with a remote controlled goniometer, the PSU for all to also be pulsed at 1 - 2 mSecs for the servo to drive the goniometer. Otherwise home-brew take a look at the G8JNJ design. A Jait of that vintage has neither experience of, or business on, HF. Any Jait of the right moral fibre and worth his salt had plenty of time to pass the 12WPM Morse test even if never intending to use the mode. |
