Subject: [amsat-bb] Split Boom for the Arrow Antenna


>I was at a swap fest lat week, and N0IMW ,Al, had a new modification
>for his Sateillite antenna, a split boom.  The orignal boom is 39"
>which is a bit long for backpacks, and suit cases. The split boom
>cuts the boom so that the longest piece is 22" when dis-assembled.
>I bought the boom and used the elements from one of my other Arrow
>Antennas.
>
>I found the boom was easy to assemble in the correct orentaion.
>the cross cut makes it so that there is only one way to assemble
>the boom.  The one thing I did have problems with is needing to
>put the director element just infront of the 70cm diven element in
>early on.  The boom does not hold together until that element is
>in.  Other than that, the antenna assembled as quickly and as
>easily as the orignal antenna.
>
>On the air, the antenna performed up to spec.  As soon as AO-27
>broke the horizon It was working.  There was no cross-talk problems
>due to the split boom, and no loss in gain over the original antenna.
>
>I do a lot of hiking and mountain climbing. It will be very nice to
>have that boom cut down, so it does not stick out of the pack.  For
>every day use, I'll keep the one in the back of the car assembled and
>keep this split boom for hiking.
>
>The new boom has not been posted on Al's web page
>(http://hometown.aol.com/qrrow146/index.html) but I'm sure if asked
>he will be able to make up more or ship one already in stock.
