I'm considering mounting a doublet type antenna on my garage and my neighbor has given me permission to use his garage given me a total length of 40+ feet. This means feeding a ladder line (or coax) out of the garage up to the roof and running most of the doublet type antenna lines some what parallel to each other. I would like to lay the antenna wiring on the garage roof without mounting off the roof. I'm considering using a commercial ladder line feed into an auto tuner and use coax from the turner to my FT-950. As of today I only use a100 watts but down the road I may wish to upgrade to something higher. I have been reading about doublet antennas to the point of information overload and I believe I can do this. The but part is I'm concerned about is what made happen to the garage roof when I transmit. Any suggestions would be appreciated. |

At higher power levels, you should use an insulator and properly support the antenna away from the roof--it is possible to start fires when running high power when the end of the antenna is in contact with combustible material. I'd suggest contacting William M. Kendrick N6RV n6rv@arrl.net He is the Technical Coordinator for Los Angeles--he may be able to put you in touch with a local expert to advise you on how to best install your antenna.
