theory (equations) of the WG antenna says that the resonance is ONLY affected by
the WIDE dimension. Changing the narrow dimension has almost zero effect on the
antenna.</SPAN></FONT></DIV>

antenna<BR><BR></FONT></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><BR>
