1. [Towertalk] 40M 4 Sq vs. 2 el Yagi at 70 ft (score: 1): Author: wz7i@arrl.net (Wes Cosand); Date: Fri, 11 Oct 2002 20:59:51 -0400; K7LXC's recent comment about yagis vs. 4 square arrays got me thinking. Has someone done a careful comparison of these two antennas for 40 meters? I have relocated and have to build a new station and; /archives//html/Towertalk/2002-10/msg00417.html (9,095 bytes)

Suggest to any one of them that they should replace it with a four-square and see; /archives//html/Towertalk/2002-10/msg00421.html (10,897 bytes)

At 75 ft or so it is a very good 40 meter antenna. This was first suggested by Ed, W8BEB and has been used successfully by many.

5. [Towertalk] 40M 4 Sq vs. 2 el Yagi at 70 ft (score: 1): Author: w5lu@hotmail.com (S. J. Blackwell); Date: Sat, 12 Oct 2002 13:21:37 +0000; What about a 3el 1/4 wave vertical yagi? (see ON4UN book for 160 and 80) This would seem to have many of the advantages of both 4SQ and shorty 40. The yagi seems easier to tune and has good gain and; /archives//html/Towertalk/2002-10/msg00426.html (9,434 bytes)

In A/B comparisons there was no clear; /archives//html/Towertalk/2002-10/msg00430.html (13,067 bytes)

The current maximum in your conductors is many feet off the ground. (How high was the center of the lazy vee dipoles?) A; /archives//html/Towertalk/2002-10/msg00437.html (15,121 bytes)

I have a 4-element lazy-vee parasitic array, and have modeled the array fed as a 4-square. ~6 dBi is the best you; /archives//html/Towertalk/2002-10/msg00439.html (9,194 bytes)

Since then 2 more TH-7s were added to the tower with the 4 square dropped lower and the centers only about 30 feet.
