It appears that the answer, mistakenly, relates to an external antenna to increase the output range. I think the questioner was looking for the same info as I am, as to increasing the range for incoming signal.
I, somehow, believe that the FCC has rules that relate to how you can enhance your connection, forcing the manufacturer, Novatel to be evasive about the functionality of the "diagnostic" port.
This idea may be a little far fetched, but, from articles I read back when the Sleek was being developed, there was a bit of resistance from the FCC to allow one to gain a connection advantage by use of this device. It was believed that distant users could bump access from users located in closer tower proximity.
Yes it does have an antenna port.
It is on top same side as power switch. The cover is a little difficult. Just lift straight up.
I glued a 12 inch pie plate with dicor on the roof of my trailer.
The pie plate was grounded to the trailer frame.
Thus the pie plate serves as a magnetic base for my magnetic antenna and a ground plane for the antenna.
It does work with a significant increase in signal strength.
My 5th wheel has the groilla cage aluminum frame which is not good for radio signals inside the trailer.
Search for antenna adaptors and antennas for the 6620L.
I was thinking of using a yagi or Trucker, which has its own ground plane.
