Locked Re: MFJ-1786 versus MFJ-1788

If 40m is mandatory and u are involved in local EmComms use the 1788. I have a 1786 since 1995 and actually I have a single element delta loop on 10. I use the loop on 30 ... 12m, installed at H pol. But if comparing signals on 10, the delta loop is at least a "S unit" better. Both are at the same height above my home (~6m). Yes, they are vy sharp, and on the lower bands sometimes I need to readjust after a few hours. On contests is a bit inefficient due to frequent re-tune when changing band or even frequencies inside the same band.

I remember the manual / advertisements on late 90s where they say the 1786 should perform as a dipole at the same height on 30MHz and -6dB at 10MHz. At that time I consider the Isoloop as well.

I have decided on either the MFJ-1786 (10 to 30 meters) or the MFJ-1788 (15 to 40 meters) mag loop for my sole HF antenna.
