If you worked HI3/KL7JR  I was on from Cabarete, Dominican Republic or HH2/KL7JR from northeast of Port-au-Prince, Haiti.  See pic for view off our Dom Rep patio and my DX window, a DX window you can take a photo of, hi hi!!  I am using a 3/4 WL 20m vertical loop (nearly square configuration with air choke wrapped around driftwood in lower right of photo.  Bottom of pic is feed point for 10 and 12m rectangular loop partially nested inside 20m loop.  PVC T's used as center insulators. Both loops (#14 wire) are hung from the ceiling of our 3rd floor (top) patio. I had great success with my 20m loop  for the past 5 years. It's 1 WL on 17m plus a 5 ft coil to get it to .75 WL on 20m.  Without the coil it does not load on 20m with my TS-570DG internal tuner. It is the most forgiving and best performing of all antennas I've tried from the balcony laced with rebar in the walls, floor and ceiling.    The performance on 10 and 12m was ok on the 20m loop, but I wanted "more" (don't we all!) so I added a 10m rectangular loop. It flat out gives me 2 "S" units better signals on 10 and 12m!  I love loops!  Cabarete is on the north side of Hispaniola Island which is shared with Haiti.  This is the 1st time I've worked from multiple countries on the same island!

My latest book, "STEALTH and PORTABILITY: Using CB Antennas on the Amateur Bands", demonstrates just how good some 11m verticals are on 10-40m when used as verticals, monopoles, dipoles and V beams. A bonus chapter is devoted entirely to MFJ mobile verticals and what can be done with them! Large print, easy to read and informative on modifying CB and other verticals. 49 pages slam full of decades of experimenting experience with CB antennas on the ham bands!

Lately I'm in to the "minimalistic" approach when it comes to antennas. I know what the big antennas can do, but just how far can a small mobile vertical antenna go? From the Dominican Republic I literally worked the world on 10 and 12m using a 23 inch tall chopped CB mobile vertical-Wilson FGT-2 with no tip mounted to an old whiskey barrel. I caused many a pile up too and what a blast it was! Later I added a 20 inch pizza tin plate on top of the barrel to broaden the groundplane (besides the close proximity to the ocean!) and grounded it to the staves and antenna connector. I eliminated the ground radials making it even more stealthy. Believe me when I say this was one little HOT aerial!!! I'm now using a dual band 17 & 15m FGT-2 vertical and a 20m vertical from the Dom Rep.

A 20m MFJ mini-mobile vertical mounted on a 4 ft mast attached to my RV ladder was my main antenna while we camped/lived at a temporary job in Richland, WA. In just one weekend of casual operating on 20m, I worked 26 states including Hawaii and Alaska, Aruba, Cuba, France, Ontario and Alberta on this little vertical that's only 24 inches tall and a 4 inch long whip for 20m! In SC I'm using a 45 ft long End Fed wire ten feet above my RV roof. Wire works great 10-20m and I have several DX contacts in the log.

 

Here's what I've done with mobile MFJ and CB verticals on the ham bands.....now where's that guy who says CB antennas don't work on the ham bands, hi hi!

My rigs: Two TS-570D's and two TS-50s. Yes, I'm a Kenwood guy! I even had a TS-590S that spent more time getting repaired than my patience would allow- hi hi!
