Im thinking of making my Ed Fong J-Pole roll up dual-band antenna permanent outdoors, by putting it outside sealed in a narrow PVC pipe clamped to the house. Is this a good idea?  Is there a better similar idea I should consider?  Different roll up antenna?

 

Gracias amigos.

If you put a roll-up twinlead antenna into a pvc pipe the velocity factor of the twinlead may change (according to Ed Fong’s videos and I don’t know nearly as much as he does), which would shift the tuning of the antenna. I would do as @UncleYoda suggests and put an antenna analyzer on it before and after. You might need to shorten the twinlead some.

Why would you buy the roll up version if you are going to stick it in PVC like the standard version? His instructions are very specific on the type of PVC pipe to buy that it is designed to work with, anything different changes it's effectiveness and match. I'd suggest buy the other one for next to nothing and put it in PVC.

I made a PVC type "hanger" for my slim jim. Was supposed to be temporary, but it's been there for over a year now. It's the arrow in the photo (sorry, it's the only photo I had available, but you can see what I mean)
