Antenna material question.

The 102" is a very well known antenna and one of the best choices in a mobile set up but its made of stainless steel....Seeing so its not very conductive when compared to say aluminum/copper/silver,how does it compare if you had a 102 made of the more conductive metals??

I ask partly cause i had a 102 (cut threaded end off)on a 10" aluminum riser that i could adjust whip length..Mind you it worked great on my plascadia but cause of my discovery and my child like excitement to install and test i didnt use any antisieze and now its one solid unit....

Anyways i now have a stainless steel version and wonder if at all it affects signal vs the same riser in aluminum??

 

Yeah i bought 3 last yr or the yr before...Used one on my cascadia and it worked great...Like i said i was just wondering how ss vs alum affects signal..
I did more digging myself and so far it seems to make almost no diff re signal..
