Hello Martin,
I have the MFJ 1786, which is the same antenna as the 1788 except that the
range is 10-30m. The range of the 1788 is 15-40m.
The loop is formed from heavy-walled aluminum tubing and is welded to the
butterfly tuning capacitor to minimize losses. Mine has been out in the
Colorado weather for about five years without any noticeable deterioration
and the antenna works well. I have used it in both vertical and horizontal
orientations with good success.
I like the convenience of a single feed-line connection, with the tuning
control signal superimposed on the coax, avoiding the need for a separate
control line. The built-in cross-needle PWR/SWR meter is a nice touch, too.
