[600MRG] Telescopic Mast Vertical - Question

[Andy - KU4XR]

Hi all:

My recent antenna debacle is forcing me ( a good thing kinda ) to come up with a better and more permanent
design.. After considering several types of setups, financial considerations, and one man maintenance has me
settled on using a 40' Telescopic Mast as a Vertical radiator.. I have 2 questions :

#1: I will insulate the mast from ground.. How high above ground should I try to get the mast ? minimum & optimum

#2: I have no other place to mount the mast but to the side of my mobile home.. Lots of aluminum siding up
10 feet high, and , a metal roof .. I will use a stand off bracket to hold the mast at 10' AGL to the side of the
mobile home.. it will be insulated ( mast wrapped with electrical tape ) - best I can do, and use dacron rope
to guy the mast with porcelain insulators on the mast end .. Top Loading connected at the top section,
and RF fed at the bottom of mast..

I realize the coupling, and interaction effects of being beside the metal body of the mobile home, so , will that
make Question #1 a moot point ?

Thanks for any comments.. Hope to be back on the air soon:
