I have two gray line antennas both with 4 foot extensions on them. I have a 24 foot with a 4 foot extension making 28 and a 20 foot with a 4 foot extension making 24. I have used both of these antennas and made contacts all over the world. I have an all continent award. I also have friendship awards on all bands 80 through 6 m I can tune 160 m as well. Only one contact on there because the band conditions have been poor not the antenna’s fault. These things are fabulous if you live in an HOA or an area where you just need a vertical Off Center fed dipole. Grayline , customer support and antenna quality are unsurpassed. These are aircraft quality, aluminum and hardware unmatchable in the regular antenna industry. These things are Support poles very lightweight. You can install it yourself but extremely thick sidewall tubing. This antenna will stand a lifetime of weather very inconspicuous and no problem working worldwide with only 100 W With an amplifier this thing would be unbeatable in contesting.
