<DIV><FONT face=Arial size=2>I would use a piece of aluminum instead, you can
get a 1M piece from Capral aluminum or any other aluminum place for quite cheap,
They are much better than a downpipe as they don't flex, dint or bend. If you
make and aluminum one it will be the only item in your setup that will last the
longest. You can also tap the connector threads into the aluminum. Trust me i
make them.</FONT></DIV>

antenna</DIV>
<DIV><BR></DIV>
<DIV><!--StartFragment --> Hi Guys & Gals,<BR><BR>I am looking at
building a drain pipe, downpipe, waveguide antenna (whatever you want to call
it). I have been looking at the various<BR>styles of downpipe that are
available. There are 2 main ones from what I see. Both have the
joining fold on one side, while one is flat on the other<BR>and one has a
slight "dimple" along its length. While I reckon the flat sided one is
best, has anyone got ideas of their own on the type of downpipe<BR>best
suited? <BR><BR>Does the join adversly affect the performance? I plan on
a single sided antenna. (3 actually, set them up like a cellular phone antenna
system.)<BR><BR>Any hints, things to look for, anything of interest anyone can
tell me prior to stuffing it up for myself :>) would be
helpful.<BR><BR>Regards<BR><BR>Mark </DIV>
