[SixClub] FD 2004

We always think of it in terms of 1,000'.  Same thing I guess.

First, we don't use the "circle" as such, quite.  We think of it as a 1,000' 
straight line, which partly addresses your question.  We put the antennas in 
a straight line, north/south, with all the antennas pointed west.  Being on 
the east coast we can do that.  West coast would point east.  "In the 
middle" could have antennas pointed both ways, fed together, which is more 
of a hassle, but at least the guys in the middle are least distance from 
either coast so they get an advantage there.

By having all the antennas broadside we reduce our inter-station 
interference.  We space them apart as much as we can.  With 10 towers on a 
1,000' line, that's nine "spaces" between towers, so they're approximately 
110' apart.  We don't have any rotators (we're talking HF here) and 
(basically) don't allow anyone to turn their antenna.  If someone wanted to 
turn it east that'd be okay and we've occasionally done that to try to work 
Europe.  We have two yagis on each band, 40, 20, 15 and 10 and we try to 
separate the two antennas that are on the same band by as much as possible, 
given the constraint of feedline losses.  So, the tens are closer together 
than the 15s, that are closer together than the 20s, that are closer 
together than the 40s, etc.  We have a dedicated station and operator on 
each bandmode -- that is, 40 CW and 40 phone, etc., which is why we have two 
yagis for each.  We also have two dipoles, one each for phone and CW, on 40, 
but on the other bands they each have just the one antenna.

On our south-most tower we have a tribander for our Get on the Air station 
(beginners or inactive ops) and our north-most tower we have a tribander, 
plus 80M and 40M dipoles or inverted Vs, for RTTY.

Our largest interference problems are not from one band to another band but 
within the same band.  We sometimes (often) have a CW station, a SSB 
station, and a RTTY/PSK station all on the same band.

We do have bandpass filters on each rig and they help a lot.  And, at the 
100-150W level, these issues are easier to handle than at the 1500W level.

Since this is the SixClub reflector... we have a separate VHF+ station that 
had 6, 2, 222 and 432, and really enjoyed the 6M propagation this time, and 
we have a 902 and up station that pretty much covers all the higher bands. 
And, they are not on the 1,000' line -- we use some of the "circle" for 
them.  hi.
