Flashing the wrong radio is quickest way to brick your phone. Have you updated to 4.1.2? This included a new baseband. I noticed a marginal improvement in my low reception areas at work. The actual physical antenna on the HD might be larger because the frame is bigger. That could be the cause of better reception.
Here is a link to the components of 4.1.2, all seperated into individual images. My bootloader is unlocked and I never updated to Verizon's 4.1.2 update. I'm running a 4.1.1 ROM and I flashed the 4.1.2 radio with no problem.
