Hi,

I will be rebuilding several 4-squares this season as well as restringing them 
in different trees due to Tornado damage (loss or destruction of many trees at 
my qth) during Tropical Storm Isaias on August 4th.  I have a few questions for 
which I would appreciate your guidance....

1) If I recall correctly, for purposes of focusing on Europe, ideally I would 
want to put the 4 elements in a box formation in the NE, SE, SW and NW 
directions relative to the middle of the array.  Is that correct?

2) In the 4-square when I select the controller direction NE, I am effectively 
radiating broadside NE from the NW and SE elements.  Is that correct?

3) In the past I had the bottom of the 4-square elements soldered to center 
conductor of the pin of an SO239 with the radials attached to each of the SO239 
screw holes, with the coax connector for the phasing line screwed onto the 
SO239.   (The choke was located below the PL259 on the phasing line) This 
worked well but I am trying to improve the design.

If I were to terminate the bottom of the 4-square element by twisting it 
through and around one hole of the porcelain insulator and soldering it there, 
would I still be able to then solder a small wire from that connection to the 
center conductor pin of a SO239 with the radials attached to the SO239 screw 
holes as before?  My idea being that I can do that then I can use a piece of 
twine through the remaining porcelain insulator hole taped to the coax to 
provide additional physical support for the coax and radials – which will be 
helpful during ice storms.

I would appreciate any thoughts and suggestions and possible improvements on 
this design.

Tnx  & 73

Bob, KQ2M
