Hi oM
I'm Pasquale IW0HEX, I live in Rome, ITALY
I bought a tribander antenna, Cushcraft X7, second hand (used) from OM
in South Italy.
Now I have 2 manuals of this antenna, one original and one download on
cushcraft homepage by internet.
There are some difference into 2 manuals about element's lenght.
In details :

Element Original manual (8/98) Download manual (12/97)

1 220" 220"
2 147-1/2" 147-1/2"
3 205-1/2" 208" (difference !!)
4 140" 137" (difference !!)
5 111" 111"
6 83" 86" (difference !!)
7 75" - 7" - 29" 77" - 7" - 35" (difference !!)

Last element (7) is trapped so it's divided in 3 parts (2 traps)

My question is : which are the rights lenghts ?????
Who has installed this antenna can help me ????
Tnx in advance.

Pasquale, the measurements you list in the original manual is the same
as in my manual, the date on my manual is 5/99.
I put the antenna up about a year ago and using those measurements it
works great without any tuning.
The tuner in the radio will also tune it on 24 and 28 Mhz, I also was
able to tune it on 40 meters.
