[Elecraft] [K3] MFJ-1786 Antenna

[Dr John H Farmer]

Hi Dave,

I've used an MFJ 1786 for some years now and my experience has been positive. It's not a beam at 100ft, but over many hundreds of QSOs,  the reports I've received and sent compare favorably with a wire doublet up at 40 feet. There's a learning curve associated with tuning it, but once you have the knack, it's very quick. Yes, the bandwidth is VERY narrow and you must get the loop precisely tuned to work anyone. You can't get it nearly to resonance and then force feed the part-tuned loop with an external tuner. 

I've worked a lot of QRP DX with my MFJ 1786. It's fun and very compact. 

73,
John
