ANTENNA MOUNTING:
 There are several ways to mount the LPA to a tower or a rotator.
 All this depends on what you are looking for in an LPA.
 The LPA can be mounted at the back-end or in the middle.
 It can be mounted to a rotator or to the side of a tower.
 It can be stacked,arm mounted,or all by itself.
 It can pretty much be treated like a yagi.
KINKS:
 When mounting the LPA (not to be confused with the LPDA) the antenna 
should*
be mounted to a nonconductive support. The antenna is balanced and no part of
the LPA is unbalanced.
 This is not the case in the LPDA where the boom is independent of the 
ntenna
elements. Both booms in the LPA are part of the antenna and are an active 
art
of the antenna.  They are the feed elements of the antenna unlike the LPDA.
==========================================================
         *** DO NOT MAKE A METAL PLATE TO MOUNT THE LPA ***
 All this will do is short the two booms together and effectively destroy
the antenna as an LPA!
==========================================================
 Mounting the LPA via the end mount way can be accomplish in two ways;
 first a fixed mount directed to a particular station or area of interest.
 Also the end mount can be put on a rotator provided that the amateur balance
the weight load of the LPA with a counter weight or another antenna 180 
egree
out from the LPA.
 You can use U-bolts provided they do not touch or even come close to 
ouching
but use a non-conductive plate like wood or plexiglass.
 PVC mounting works well and frequencies below 2 GHz.
