Using nylon tube as an antenna protective sleeve

[flyingw]

Jim, 

In a new installation I want to use some lengths of the inner tubing from a nylon pushrod as guides for the tips of the RFU antenna.

Will that type of nylon reduce the range of the RFU?

How about a thin plastic coffee stirrer?

And, the small, thinly-spread amount of epoxy to glue the tubes to the wood.

thanks,

Paul
