Topband: Using a Tower to Support an Inverted L

[Udo A. Heinze]

I just replaced my low 160 meter dipole with an Inverted L to improve my transmitting signal.  The Inverted L is about 2 feet from a crank up tower I use on other bands.

Here is the general layout:
Tower height is 55 ft.  On top is a 4 element WRC tri-bander and 8 feet above is a 2 element M2 shortened 40 meter yagi.
The inverted L is 55 ft vertical about 2 feet from the tower, then 80 ft horizontal.  Single wire (#13 copper).
The radial system is buried 40 wires 100-135 ft long.

After installation I got the following readings at the base of the antenna:  SWR increases from 1.2 to 1.6 (1.800 - 2.000 Mhtz)
              Measured "Resistance" was 52-77 ohms;  Reactance 7-18 ohms (using MFJ 259B)

There is obvious interaction between the "L" and the Tower/Yagis.  Has anyone had experience with or modeled such a setup?  I am really curious as to
what  I can expect from this setup. Thanks for any help you can provide.
