[TowerTalk] Polyrod vs Philly vs 502s

[Paul Bittner]

WDGY, 50 KW AM station in Mpls/St Paul had one of their 9 towers go down in 
a wind storm because Philly failed.

The station noted the bulb life was greatly diminished....they believed it 
was vibration of the tower...

They were told to put lead weights on the bottom side of the cable...

They did, but apparently the Crosby clamps holding the lead weights were too 
tight, weakened the cable and the one of the cables broke...the end, 240 
foot tower went down.

At that point WDGY put the nice dampeners on the cable and that must have 
eliminated the problem.

Well, WDGY relocated and I took down the  other 8 towers with all the heliax 
and philly.

I like philly but it is $$ so use mostly many eggs & preforms.

Now you have  some  not silly philly story.
