    Second try.Yes I'm using coax feed line with 6 inch 6 coiled balums on all my antennas.I'd like to try and contact some of you on 28.400 when get it back up.I'll be K4ECE.

    Some of the older Islanders have the same problem, however, it has nothing to do with antennas.

    But if you want to go with a coax fed and no tuner you can do a fan dipole or something similar.
    I could never hold reasonable SWR on 40m with my 75m Vee. Worked wonders on 75/20m though. I have used fans as well with good results. Ended up putting up a loop for 75/80. I found myself transmitting on the loop and receiving on the Vee.

    There is a catch. Yes you can do that but you'll have nulls on the higher bands. It won't be omni.

    But yes, it works in a pinch.

    What's a balum?
    I am surprised at such a sudden deterioration in a woman whose only ailment was a lazy anus.

    I recall an article by W4RNL (SK) showing antenna plots that show an Inverted Vee cut for lower bands and used on higher frequencies also quickly becomes a cloud warmer... When to far removed from the fundamental frequency it's cut for.

    Not too useful on 10 meters. Make it a fan.

    Got my fan inverted v back up.instead of single point conection I seperated the 40 meter from the 10 meter by 6 inches.I haven't checked the swr yet but I made a contact with El Salvador on my 25 watt Radio Shack 10 meter transciever.
