[TowerTalk] polyrod

[k3mm@comcast.net]

Realize that black rod in a coil or encased in black corrigated drain tube as a shipping container and exposed to sunlight will get very hot, even if the ambient temperature is not high.

In a coil, there is no or uneven air circulation as well.

This probably contributed to our coiled failures.  Even tho it was received during the Winter, much of it layed around til at least early Spring as I recall.  However, I know I had failures of a coil that was laying in shade (in a run-in shed) most of the time.

So, yes, if you decide to leave it coiled, store it in a shady place...even better a temperature controlled place...or paint the coil white...or order white rod!
