      • Many RASON members truly enjoyed last month's collinear antenna. This month I decided to build a 2 meter 5/4 wave antenna. This antenna is unique in that it is enclosed entirely in 3/4" PVC which makes the design a little more complicated. The primary problem is that PVC tubing has a significant velocity factor which causes RF to slow down.
    • And most of the 2m stations he was working had towers, high-gain arrays, and linear amplifiers as well! *(Having said that, with that nice array Dave heard so many stations that it sounded like a contest on 20 meters! :-) Now you see what kind of challenge you face if you want to work from coast-to-coast on 2 meters.
      • Of course, if one has no choice as to location, a high-gain antenna in a poor location is still better than a low-gain antenna in a poor location. But never, ever skimp on coax for VHF/UHF/SHF work. With this above in mind - I suggest using 1/2" hardline (not SuperFlex) or Times-Microwave LMR-600 for your main coax run, if you can afford to.
