[TowerTalk] Performance of the C4/E on Warc and 40 M?

[kd4rwn@bellsouth.net]

Hello All,

	I am about to undertake some Antenna Upgrades and was 
considering the C4/E family for the new primary beam. It would 
replace an aging Th-6 (Which would probably just move 30 ft down 
the tower). A little background first. The Tower is 40 ft of Rohn 25, 
but the Tower is mounted on the 5th floor of the building, on one of 
the sides. So the beams' height is really about 100 ft. This is for a 
University Club Station. My questions are the following:

1. How does the C4/E family perform on the Warc Bands? I know 
it’s not designed for it, but it does have gain.. We have tuners so 
that’s not a problem. How does it compare to, let’s say, the 3 
element Warc from Cushcraft or other similar sized beams?

2. How does it perform on 40 M? We currently have up a 1/2 Wave 
Dipole at 35 feet, Beaming EU/SW. The takeoff angle is a wee bit 
high, but it does get out. The 40 Element of the C4 would be about 
10 ft higher. I know the Bandwidth is about 1/2 of the dipole, But 
would performance differences can we expect, Especially for DX?

Thank you all in advance for the help. Much appreciated by this 
station...
