I have a couple of days off here next week and wanted to make a new antenna. I live in a town house and they do not allow any outside antennas. I was thinking about building a vertical that I might be able to leave up for a couple of days or until someone yells. I was thinking about this one in particular, http://www.hamuniverse.com/kl7jr5bandvertical.html My questions for you all: I have never used 1/2 and 3/4 inch EMT conduit before. I have sold the hell out of it when I worked at a hardware but never used it. For portability and storage the 10 foot length is a no go. I was thinking about cutting them down to 5 foot lengths and either using the appropriate coupler or some other sort of joining device. I'm just not sure if the EMT couplers would be strong enough to with stand a couple days of wind and weather. I wouldn't be leaving it up in bad weather unless something happened to spring up unexpectedly and I wasn't home to take it down. Thank you in advance for any help and opinions. I know I could probably buy something and it would be easier but where is the fun in that!
