> It seems to me that phasing delta loops is more trouble than it is worth.

> reflector. The gain and impedance curves will be a lot flatter.
> If it is up too high to be able to trim the reflector for best f/b,
> you can add a quarter- or half-wave stub and adjust your open- or
> short-circuited stub closer to ground level. If you want beam reversal and
> your supports allow, use a common reflector with a 'driven element' placed
> on each side and feed one or the other according to which direction you
> want to fire in.

Has some mailer gone berserk somewhere?  I have now received this
message 6 times.  It's the same message -- verified by the Message-ID
line.
