Topband: FW: CQWW a bust this year

[donovanf at erols.com]

Flexible coaxial cable jackets are easily damaged by careless handling, 
by mice and other vermin, by improper installation on a tower, or by 
not bonding the coax to the top and bottom of the tower which makes 
it susceptible to pin hole damage during lightning strikes.

Another urban myth -- coax is degraded only 1) by the intrusion of 
moisture into the dielectric, which occurs at poorly installed or poorly 
weatherproof connectors or with physical damage to the outer jacket; or 
2) UV breakdown to a non-UV-resistant jacket.

YES! There's an app note for this on my website that ran in NCJ several 
years ago. k9yc.com/publish.htm
