[Jim Tetlow]

Hi Jim, let me get back to you, I with be meeting with one of the authors at lunch today (Shawn n3ae). If not too late you are welcome to join us, Mt Hope Community center in Sunderland off Rt 2 and Pushaw Station Rd; around 12 noon or so. If you can make it, great, if not I will get you more information, and any improvements we may try.
73,

I know if you increase the height of the mast to  > 30 feet its harder to raise and support, and it changes the angle, maybe Shawn could look at that with the antenna modeling program? Smaller footprint might make easier placement? But 30 ft may be too tall. Somewhere in my collections of stuff I have a surplus army antenna mast field kit for NVIS antenna, these are tapered poles that go together and need guying, but I think it approaches 26-30 ft tall.
