[MilCom] HF Antenna for Ute monitoring orientation question

[Ron]

    Have pulled down my Grove Skywire from the old house in NE MA which had 
one end north and the other south so it was actually oriented best for 
east/west reception? Had no other options due to small lot size and tree 
locations. Worked it with a Uniden SW radio and a RS DX392 with fairly good 
results across the frequency range but with 1/3 acre lots and lots of 
neighbors all around had considerable interference. Only used it for mil ute 
monitoring.
    Now have 2.5+ acres in southern NH with closest  neighbors about 300+ 
feet away to East, South  and West.
    Easiest mount is from house to barn, again almost identical orientation 
as MA location, but could also go with one end  ENE, E or WNW by using house 
to trees. Will be hooking it up to a Gary Weingard refurbed Racal 6790.
    What is the 'best' option for single antenna orientation?
    Should the Longwire be grounded to a grounding rod before feeding into 
the house/radio to help remove static?
    Any other tips from you folks who have been there, done that, got the t 
shirt (or fried the rig) and would like to keep me from reliving your 
experiences?
    Any suggestions for a 'better' antenna type/make?
    Contact off list if preferred and pointers to any web sites (please, not 
nerd level ham antenna discussion sites!) that will give further basic HF 
reception antenna installation/operation guidance appreciated.
