[SEDXC] Mosley TH-3jr Weirdness

[Rich Arland]

H Gang:

I have a very strange request for info. I inherited a Mosley TH-3jr tri-bander from Russ, AE4NY. The driven element has two (2) 7ft 3 inch pieces of multi-strand wire (NOT coax) in a very heavy insulation running from the SO=239 down each side of the driven element. I have never seen this before. The length does not equate to any ham band covered by the antenna (it covers 20/15 &10M). As near as I can tell each piece of wire sits inside the aluminum tubing and the is connected to the coaxial connected but for what purpose I haven't the faintest. 

So, anyone have an idea as to why this insulated wire sits inside the DE on this tri-bander?? I have photos that I will send to anyone who wants to have a look. I don't want to attach them to this mssg as it is going to several lists. Any info or ideas would be of help as this antenna is due to go up in the air hopefully this weekend. Pls reply off list. 
Tnx
