- Folks I have a question, and judging by the pass you all are so expert and helpful I have no doubt you will be able to answer with authority. I am going to mount a short 8' high tower on the roof (co

- In my opinion it is not worth the trouble. Also...no need for 1/2" radials, even if they are free. Save the tubing and find another use for it. #24 hook up wire would be just fine for radials. The mo

- George, Yes, 1/4 WL verticals absolutely need radials. Elevated (Vertical) Ground Plane antennas work best with resonant 1/4 wavelength (WL) radials. Verticals on the ground work best with 30 or more

- Hi George, I think "Ask the Doctor", in QST, gave an incorrect answer to the very same question you are asking. I *think* they said if you flattened the conductor, the resistance would decrease, but

- A 2.4m roof tower will be too short for your final antenna, unless you are thinking of 50 or 70 Mc. Even at more than twice that height, I find too much interaction with the roof at 14 Mc with a trib

- I expect there is considerable difference between concrete and structural steel roofs and conventional wooden / shingle home roofs. Unfortunately, George did not specify which type he had. Tom N4KG _
