Hi All:
First off I want to thank every one who sent their comments to
my question about the 3/3 stack vs a 5 el mono.
The main consensus was to go with the stack, although one gent
said to go with a 5 over 5 stack. (I wish I could)
So after getting the "real world" view I went to my computer to see
what it though. I used an old (read 386 compatible) copy of MN.
Here is what I came up with.
Using 20 meters as a start. The 3 elem stack at 50 feet and 94 feet.
The 5 elem on 40 foot boom at 72 feet.
3 over 3 5 el mono
Forward gain at 5 deg. 9.6 Dbd 8.06Dbd
F/B 16.87 13.88
Az. Beam width 64 deg. 54 deg.
Angle of Rad. 12 deg. & 13.69 Dbd 12 deg. & 12.65 Dbd
I picked 5 deg for F/G "Just Because" (no real reason)
It has been a real interesting exercise to do this. Now I will
have to order a 103BA from Hi-Gain to match the one I already have
and rework my 5 elem to be pointed at EU.
As ever any comments should be sent to me.
