I installed a vertical with ground radial kit up 20 feet. The antenna mast and negative sheild connector is grounded to a ground rod. The antenna covers 10 to 40 meters. I can tune 10 meters fine, and fourty meters fine, but 12,15,17,20,and 30 will not tune and SWR are high. here are the SWR reading taken on AM running 25 watts.
10 meter 2804550 is 2 to 1 SWR 2882000 is 1.5 to 1 SWR 12 meter 2490000 is 3 to 1 SWR 24990 is 3 to 1 SWR 15 meter 2103900 is 4 to 1 SWR top porting is 3 to 1 SWR 17 meter 1809000 is 3 to 1 SWR 1817000 is 2 to 1 SWR 20 meter 1402800 is 2 to 1 SWR 1430000 is 2 to 1 SWR 30 meter 1010500 is 4 to 1 SWR 1014000 is 4 to 1 SWR 40 meter 7026 is 2 to 1 SWR 7290 is 1.5 to 1 SWR Any help or suggestions would be greatly appreciated. I will be receiving my K3 on Tuesday and am trying to get this antenna sorted out before then. Oh yea the rig I'm using right now is a Kenwood 570, the Coax is LMR400 with a 100' run. the Antenna is a ZeroFive GP10-40.
