I have Z3816A's and TBolt's. Both do a great job. For the TBolt, I use
TBoltMon.exe to monitor and for the Z3816A, I use SatStat. The Z3816A
requires a 'null modem' adapter or an appropriately wired serial cable to
connect to the serial port of the computer where as the TBolt uses a
straight serial cable.
The only potential advantage of the Z3815A that I know of is the fact that
it uses the E1938A oscillator. I have a couple of these oscillators and
they are superior in performance. However, I have no firsthand knowledge of
performance of the Z3816A versus the Z3815A.
The Z3816A and the TBolt tracks up to 8 satellites. The Z3816A also tells
you what other satellites are under consideration but are not being tracked,
perhaps up to 8 other non-used satellites. I have at most seen the Z3816A
refer to a total of 11 satellites (8 tracked and 3 not tracked) but my
antenna is not in an ideal location. I do not know about the Z3815A. The
Z3805A tracks up to 12 satellites, if I recall correctly, and probably
should also be included in the comparison list if you are looking for a
The Z3816A comes in at least two variants, one powered by a DC supply (I use
30 VDC for mine) and the other powered by 120 VAC. I don't know about the

Is there any downside to a model Z3816A? I also see a Z3815A on Ebay, but
the connector arrangement is not attractive. Does anyone have a link to a
comparison chart between all these models?
