    GAP 15m Mono takes on my Hustler 6BTV on 15 m and wins hands down. Tuned at 1.2:1 with no adjustments on 15m after assembly. It tuned 1:1 on 17m. What a pleasure to see the receive gain up 3 s units over the Hustler. It is ground mounted per the instructions and is very low profile.

    I have the monogap 20 meter ground mounted. Performance on 20 is comperable to my dipole on close contacts but much better on dx. Also as a plus my Yeasu internal tuner allows use on 10, 12, 15, and 17 with performance equal to that on 20.
    definatly a keeper.

    My second Gap Vertical, a 20M mono. I purchased about 8 years ago. I use mostly for cw and psk31. If I hear it I work it.
    This antenna is a dx machine, 20M psk31, 30 watts, New Guinea and the Pacific rim. South America with S9 plus signal on psk and cw with less than 50 watts. You can add Europe as well. This antenna has been my only antenna until today, just received my third Gap.

    The third Gap is a brand new 40M mono. It isn’t up yet, however, I will have it up this weekend. Sunspots force a new antenna, hi hi. When I called Gap I explained that I have bad hand tremors. I requested if it was possible for them to do a bit of pre-assembly for me. Richard offered to help and today I have the antenna with the pre-assembly done. YES, greatly appreciated and above expectations. I may have a backyard sprouting aluminum Gap antennas.
    THANKS GAP (Richard)

    Had a Challenger back in ’93 and another one here until it went down in a tornado. I know how well they work. So bought the 40 Mono and am very pleased. Went together easily and once erected worked “right out of the box”. I’ve WSPRed down to 200 mW with good results on 40 and, surprisingly, 20M. I’m mostly QRP here and couldn’t ask for a better antenna. Thanks

    My 40 meter Gap works the world. . I now spend the night on 40 meters. This antenna is fantastic. Still waiting for a 80 meter version.
