I'm not a fan of the ground lug on the back, the biggest reason is it makes it sigifianctly more difficult to field service.
everything in the air is complicated 10 fold, if we need to replace one after the install, bending 6ga (my desired minimium ground contact) is difficult, if its on the back of the radio the person having to replace it has to free the radio from the sector, then some how hold the radio safely while disconnecting and then reconnecting the new radio, this is a saftey hazzard due to drop risk of the radio. the ground lug needs to be accessiable after the radio has been safely attached to the sector to reduce drop hazzard in my opinion.
attached is a photo of commonly used 6ga single hole ground lug. double hole lugs are the most common used for the cell carriers. i'd be happy with this sized lug contact with quarter 20 hardware, this lug is sized for 3/8 hardware.
as a side note, if you designed this lug hole to pass all the way through the radio, and makes contact near the most heat generating componet of the radios, i'm willing to bet having this thick of a ground contact would have an extra impact on the overall temp of the radio.

Chris,
That makes a lot of sense. Thanks for the visual. For the ePMP 2000, the grounding screw was moved to the back of the radio, where you can attach larger gauge cables because you are no longer limited by the tight enclosure in the radio. What are your thoughts on this placement?
Feel free to ignore the salt/fog labeling and that the grounding screw is a little smaller than it is supposed to be.
