Here are some pictures http://home.earthlink.net/~cjohnson1379/ "Chris" wrote in message nk.net... I have constructed a homeade antenna that is mounted on a trunk-lip mount on a Nissan Sentra. The bottom is 18" of 1/2" copper pipe with a 3/8" theaded adapter soldered in the bottom. There is a 9" long peice of pvc with a 2" diameter 6ga. copper coil around it. Then there is 4" more copper pipe with a 3ft' stainless tip on top. The problem is that it would be too easy to bend the trunk with copper pipe. I thought about a spring but then the whole thing would bend too much when the trunk is opened. If I move the coil down below roof level, the SWR goes way up. I thought about using pvc for the lower part but I can't quite figure out how to construct it. I may take some pictures of what I have. Stay tuned...... I saw a guy that built a mobile antenna out of copper pipe for his pickup he had a 2x4 set in the stake hole on the front passenger side of the bed, it was capacitive fed The pipe was capped at the top and held to the 2x4 with pipe anchors. Not sure how well it performed,but for a home brew job, it was rather interesting. Please forgive my crude representation, my ASCII art skills have not been used in quite a few years heheh. | | | | | | | | | | |___| |___| -------- capacitor | | | | | | ________________________ |_______| |_______coax_____________ 73 de Keith KC8TCQ Know thyself.
