Hi, Don I would definitely favor the Inverted-L configuration to maintain the high-current portion of the a antenna as a vertical radiator with the current maximum distributed as high as possible. Problem with a base loading coil is that the current maximum would be in the loading coil that isn't much of a radiator. If you could add enough light gauge wire to the top of your 80 m vertical to resonate it on 160, that would be an entirely different matter and would probably work rather well Good luck! 73, Charlie, K4OTV -----Original Message----- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Goldtr8 (KD8NNU) Sent: Saturday, August 10, 2013 7:51 AM To: topband Subject: Topband: Vertical vs inverted L question/opinions I am requesting opinions on what would work best for 160m based on a bottom loaded vertical or inverted L. I have in the past used and inverted L for 160m using a common feed with my 80m vertical. The 80m vertical has parallel wires for 40m and 20m also and it works real well with 38 radials laid down in the grass. I like to compare it to a fan dipole but only the vertical section is the multi wire part as the radials are buried. Anyway I am starting to plan for the winter season and I am wondering if a loading coil on the bottom of the vertical would yield better results than the inverted L. The L is limited to at best 50ft vertical section and the rest on trees. My thoughts are if I use the 80m vertical section I will have 68 ft of height which may be better than the L. The vertical is not structurally strong enough to add a wire or a cap hat to the top of it. Clearly I have the ability to try both and play around but I have time to make alternate plans so I am fishing for opinions and or suggestions. ~73 Don KD8NNU -.- -.. ---.. -. -. ..- _________________ Topband Reflector _________________ Topband Reflector
