10 Meter Aluminum Rotatable Dipole

I'd like to try a 10 meter rotatable horizontal dipole made of aluminum tubing. Based on lack of product availablity, I'm wondering why nobody does this. Is a vertical that much better? I suspended a wire 10 meter dipole between chimney's and it worked well, and picked up very little noise like my antron-99 vertical. Seems I could use a mast to get more height above the chimneys if I had a half wave of aluminum tubing on top of it.
Have found only one company making such a thing. Considering making my own but not sure about the exact tubing and bracketing to keep it from drooping like an unkept mustache. I like 10 and 11 meters. Not too interested in a beam or 20 or 6 meters.

    Antenna length on my mobile. So I’ve had 3 different radios in my truck. 2006 f250 super duty. 29ltd NW, 29 ltd clasic, and now a galaxy DX44HP. My steel whip is somewhere around 89”. Which I know is way to short. But show 1.2 SWR on all 3 radios. And I have a a bench SWR meter that shows the same results. Which I find odd and disturbing. Note the frequency is 27.205. The longer I make the whip the higher the SWR. At 102” it’s up around 2.5. Which totally blows any of my experience i have with mobile radio antennas. I have the antenna mounted to a post just higher than the cab. I’ve swapped the jump through several to different ones. Even tried lug and so239. Connections at the antenna. Seems to transmit well and receives well. Any ideas how this could be possible?

    Turns out I was missing the ground to the cab. Problem solved. Now have 102” exact and 1.2 SWR 26.005 megahertz through 28.005 megahertz. Pictures posted on my profile.
