[TowerTalk] Inv L's and 4 square

[Robert Shohet]

Hi 4-square fans...

I currently have an Inv L 4-square on 80 that is around my 130' tower.  The
4-square elements are elevated with elevated radials and the element ends
point AWAY from the tower and AWAY from each other.

Due to space limitations, I am contemplating hanging a pair of phased 160
Inv L's from the 115' level on my tower and angling them out away from the
tower and away from the 4-square.  The ends of the 160 Inv L's will be
elevated with elevated radials and will be phased with 3/4 wavelength
coaxial lines.  The ends of the 160 elements will be 1/2 wave apart - about
270'.  The ends will be about 100' from the 80 4square InvL elements but the
radials will come closer than that to the 80 4-square radials.

I think that some pattern degradation might result but I don't think it
should be very serious.  Any thoughts on this?  There is no other good
alternative for 160 at this qth.

All help and comments appreciated.

Many thanks and 73
