I'm beginning construction of a 10 meter antenna for installation onto the top of my palm tree. It will end up being about 35 feet above ground level to the tip of the antenna.
I have enough wire to make a 1/2 wave upper section but I am a little stumped on the bottom section. I plan to use 300 ohm twin lead for it. I need to know if simply making a 1/4 wave section using the 300 ohm twin lead, connecting it to the 1/2 wave section above it, and then simply tuning it by finding a resonant point near the bottom of the "J" section is all I need to do.
Is it that simple? I have made a 2 meter J-pole and it was that easy using all 1/2" copper pipe. I guess I just need to know if the 300 ohm twin lead will function as the "J" section.
Thanks and 73's de N7USR Greg
