Thank you Mike!
Whew you guys sure are helpful. From the outside wall to the top of the
School Roof it is about 60 feet. I am not sure what kind of bending
Radius the 9913 (rigid) has so I do not know how much to add on to the
length? I would guess from where the coax enters the utility room from
the outside duct (They have an MTV System on the Roof) it would be another
15 feet tops. I can run the 9913 straight to the operating station desk
using the exsisting electrical trough that the TV stuff comes in. I wonder
if it's ok just to use the standard RG-8/U on those "N" connectors for
both ends (station and Antenna)?

The Garden rake Idea is Super! I will pick that up tomorrow morning
and do just that. A friend of mine tells me not to worry too much about
the elevation control, just fix mount them about 20 -30 degrees above
the horizon, does this sound right to you? If So I am wondering if it
would more advantages to build a small 3 element quad instead of a
Yagi for two meters?
I can Pay for the shipping and if you need an offical request from
the District School Office I can get them to mail you one. Either
Way my mailing/shipping Address is good in the callbook.
Tomorrow afternoon when my wife takes her afternoon nap I am going
to finish building a powersupply for the 2 m/70 cm Amplifiers. The
amps both run up to about 100 watts SSB/CW so I have a 60 Amp
regulated powersupply nearly finished.
Thanks Once again Mike, and your concerns about my wife did not go
un-noticed. When we both learned about what she was facing it was
very difficult to accept, Lost my dad to Cancer a few years ago and
was scared stiff to lose my best friend/Wife to it. Fortunately
they appear to have caught it very early so other then the normal
sickness from the chemo and radiation (Hair falling out) we seem to
be on the way to recovery. Sure made me re-evaluate my lifestyle
and priorities.
