Ewwww, ray was correct - swr on 30m would be 38 (609+j895) on 30m,
due to the other band dipoles not being full wave etc on 30m..
Ok, will be a 40(+15)/20/10 dipole then ;) I had contemplated
shoving 5m on the bottom, but it might look kinda rediculous in
the middle..<br>

I thought I'd just make the top band 40m, and add 30 in the
middle.. Might shove it through MMANA first to see what
happens, before I finish cutting and assembling that behemoth,
and then pulling it up between the masts..

<div>I have to say I do like the dell service, where
if you order a computer with a monitor (can just be
a laptop), they pickup the old monitor for free and
dispose of it :) Though they had a heart attack
when we asked if we could dispose of 60 21" sony's
through that :-p Actually, they had enough of a
heart attack when we asked about ordering 60 LCD's
as 'spares' for our existing machines.. ;)</div>

<div>Wow, that's not bad - ACT govt charges
$50/monitor to dump them at the tip.. -
when we replaced our 21" sony CRT's with
19" LCD's back in 2005 (worked out we'd
pay back the costs of replacing 3x21" 500W
crt's with 3x19" 50W LCD's per Desk, in
just under 6 months!), we ended up shoving
them all into the dumpster out the back
over a couple of weeks..</div>
