Simple Ham Radio Antennas--Rebuild MFJ 1622 Apartment Antenna for Ham Radio HF. Post #485.

Excellent antenna rebuilding project from the "North Carolina Prepper.  Like this ham, I have an old MFJ-1622 Apartment Antenna, which I use for portable and emergency situations.  When I saw this intriguing video, I decided that some overdue maintenance on this old, reliable base-loaded vertical was in order.  The large clamp was fine.  It attached easily to the railing of my lanai (outdoor porch) at my vacation home in the Puna District of Hawaii Island. The suggestions discribed in this video are easy to implement and will improve the overall efficiency of this small antenna.  First, I replaced the stock coaxial cable feed line with some RG-8X I had in the shack. Next, I cut a counterpoise wire for each band of use (40 meters through 2 meters), rather than use the one roll out counterpoise wire supplied with the antenna kit.  Band changes are simple.  Just move the tap on the coil to find the best SWR.  I tried out the refurbished antenna later on that same day and was pleasantly surprised how well it worked.  I cut a few additional counterpoise wires (4) for each band and found the performance of the small vertical much better.  When I was done making the corrections and refinements suggested in this easy to follow tutorial, I put the antenna in a small plastic bin and stored it in the garage for my next impromptu portable operation.
