Chaparral LNBF PPL OR DRO?

I recently bought a Chaparral MicroPak 3G C-Band LNBF from the Chaparral website a few months ago. It's been working great so far with a large aluminum lamp shade attached to it to draw in the signals better

I assumed I bought a PLL LNBF, but there is no mention about it on the website or the box that it came in. I made a call to Chaparral Customer Service to ask, but the guy was new and couldn't tell me the answer either.

Could someone tell me if I bought a DRO or PLL LNFB?? I'm afraid to try to crack it apart to find out. I appreciate your help!
