Totally agree Robb...Aluminum is listed as one of the top five conductors of electricity. Steel on the other hand with all its impurity factors, never made any conductivity list, too many types or variables. Aluminum with its high resistance to corrosion has been the perfect choice for the communication industry for years. I wish my roof was aluminum!What's wrong with aluminum? So long as the roof isn't plastic or fiberglass, aluminum should work just fine. You can't use a mag mount on aluminum - of course - so a solid mount will be have to be used in its place. But it should work just fine.
Think about it for a sec; most base antennas are made of aluminum.
Have a local friend that has his antenna mounted on his fiberglass truck shell on a Ford truck. He added aluminum strips lengthwise along the inner shell and he made that work just fine. Had to add a bunch; but it works.
swr being that far back?Have to get out the drill since the mag mount is out. I tried looking up the roof of a 17 f150. Looks like you have some space between where the ridges end and the back of the roof. Might be able to pull out the 3rd break light and access the underside of the rear roof without dropping the headliner.. Or you could drop the headliner and put your hole in the middle the roof a little off center. Or look at a bed rail/steak mount...
With good coax/connections and a quality mount and antenna I don't see why not.. Locating toward the back of the cab might make it slightly directional toward the front.Would I still get a good

I dislike rust and try to avoid mag mounts whenever possible. The Velocity factor difference between the two different metals in this case will have a minuscule effect. Capacitance variations between the base of a mag mount and the body is more concerning. I’ll take a body made of aluminum over steel any day. The same goes for the truck bed. If I plan on dropping tool boxes or concrete blocks on it, I’ll buy a good bed liner. Sorry Chevy, Ford won that argument hands down. This is my opinion of course.Nothing wrong with steel either. I like my steel roof because I can use mag mounts - and do. The only difference between steels would be the velocity factor; which is no big thing. Same goes for aluminum. Velocity factor isn't exactly the same between different types of aluminum either; but it will still work. Velocity factor is a concern when building an antenna from scratch, or defining the length of a 1/2w cable at a given freq for the most part.
Can I mount a Wilson 1000 roof mount on my truck?
The body is aluminum.................... plus the roof has ridges in it damnit!!!
