Slim Jim 2 Meter Antenna Project

This project was based on the basic design from WB5MAJ, Fred Siebenthall, and I appreciate the detail that he went to in his write-up of his antenna project. This entry is for my "remote deploy build" but I have another variant mounted on a PVC staff connected to my chimney.

E-mail me if you want a copy of his pdf for a project of your own.

Here is the finished product with the exterior cover on.
Here is the top cap with nylon screw and loop for hanging the antenna up.
Here is a view of the underside of the top cap.Picture of the bottom cap with the pigtail sticking out. The pipe clamp is used to hold the cap on while providing an easy way to remove the internal antenna from the outer casing if needed.Close-up of the bottom cap with slot cut for cable exit.This is the internal PVC carrier with the antenna wire wrapped around it and the pigtail goes up through the bottom and comes out at the cutout futher up the pipe.This is a shot of the cutout and the showing the connection of the pigtail to the antenna wire. The wire goes through the 3/4 pvc pipe via drilled holes. Wire is bare 12g copper wire. Close-up of attachment to antenna wire.

Hi Keith, I am interested in making a slim jim 2 m antenna that is enclosed in pvc. I would appreciate getting a copy of WB5MAJ project pdf. I would also appreciate details of the type of pvc you used for your project as I have heard that some kinds of pvc negatively affect antenna performance. I hope this gets to you. Please email me at ki6gig@arrl.net Thanks for your time and consideration.
