I contacted Jim W6LG. I got a reply from him this morning after I posted this msg. He owns Heath Tech. He was the manufacturer of the antenna. He no longer makes them but he was willing to answer a few questions.
It appears my antenna IS missing the spring and collar assembly along with the delrin insert ring. The spring is the contact spring to make the antenna resonant as the center conductor goes up and down. It goes at the top of the metal pipe under the plastic shielding - see the picture. thats the only image I could find online in ALL THE INTERNET that showed what I need...lol
I purchased the metal collar housing and the plastic Delrin fitting insert along with a motor this morning. Next wk or the week after I will be purchasing the maintenance kit which has the outer plastic shield, metal spring and contact cleaner.
Once I have those, then all I need to do is clean the brass parts up, install the ring, delrin and collar, replace the motor and I will be good to go. I have 50ft of foam centered RG213 coming from Universal Radio.
Got my Weller solder gun from Amazon this morning in the mail. After all that, All I need to get is a tripod and some 1.5od mast, some wire for radials for 40/30/20/17/10 and I'll be on the air. Oh and I need to purchase a new mic for the 706. My original mic has been misplaced. Its in the house somewhere but I got too much shit to go through to find it...
