[TowerTalk] 4 square advice baand width enhancement

[Hans Hammarquist]

 Maybe an old-fashion ladder line would do, I mean the one with 4 - 6 inch spacers. When you will have no problem with it twisting and shorting out.



I have had thoughts using that myself but never gotten to it. I have a box full of 4 inch spacer. Maybe they can get to be of good use.

I find it hard to believe that using wire vertical instead of a freestanding
aluminum vertical with maybe a 1/2 diameter top section or even a solid 3"
irrigation pipe will make enough bandwidth difference to be concerned about.

I'm starting construction of my wire 4 square for 80 meters.

I know the bigger the diameter is (like having Rohn 25 tower for the
radiator) 
the better the bandwidth.  
I'm using #12 insulated wire, but in an effort to enhance bandwidth I'm 
planning using two wires joined at the top and at the feedpoint for each 
element.  To space them  I'm using some old KLM diamond shaped spacers every

five feet or so to keep the two wires approximately 5 or 6 inches from each 
other...running the wires parallel to each other.

Any thoughts as to how helpful this will be in increasing bandwidth?  I have

about 45 of these spacers and they're just gathering dust, and they are 
lightweight, UV resistant and free.  Also, any thoughts as to how this might

affect the impedance etc.?
