Re: [Repeater-Builder] 2m quad

[Al Allum]

Hi Sandeep,   I have made a 3 element quad for 2 meters.  I used 3/4 inch PVC (stronger then 1/2 inch) for the mast and got two of those fiberglass flag poles that you put on bicycles to use as the spreaders.  Just drilled apposing holes to hold the spreaders and used epoxy to secure them.  I used the dimensions from the ARRL handbook.  Copper wire is the best.  You will make it either vertically polarized by feeding in on the side in the middle or horizontally polarized by feeding it in the middle on the bottom. For the driven element I left about 1 1/2 inches extra on each leg which I turned up at a 90 degree angle and used it to tune the antenna to the frequency I wanted by attaching the coax  higher or lower on the two ends. Have fun.   Al, N8ARO       ----- Original Message ----- From: Sandeep To: Repeater-Builder@yahoogroups.com Sent: Wednesday, January 28, 2004 11:50 PM Subject: [Repeater-Builder] 2m quad Hi this is off topic I am planning a 2M cubical quad, four elements. I have gone through the article in ARRL hanbook about 4 element portable quad. My questions are 1. I am using solid copper wire 4 mm dia, are those dimensions ok? 2. Anything against using a conducting boom? i propose to use 1.5 " aluminium pipe or square section thanks Sandeep VU2BX Yahoo!
