Recommended Accessory Use for Maximizing Performance:
The remote antenna generally has a higher gain than the pop up, and
an inexpensive PVC range pole will assist in tracking in canopy environments.
With some exceptions, this is the optimum method for the best position fixes.
Cable problems, snagging on tree branches can be reduced with the new bottom
exit AERO antenna available from 3D as an alternative high gain antenna. Based
on field trials (open sky) this alternative antenna yields a 2-5 db gain
(higher C/N ratio by 2-5 units) over the hockey puck type remote antenna from
Rockwell, and the bottom threads can be mounted with a ¾” PVC adapter to an
inexpensive range pole. These will become available in December, 1999 as an
alternative. Beginning in December, 1999, the 3D company will also supply the
PLGR accessory kit at a reduced rate from the accessory total from Rockwell.
Cable for the remote antenna has been a weak link. The SMA connectors
pull loose over time. Order a flexible 3.1- meter replacement cable from 3D for
$53.

Use external power to protect your performance. The AA holders and
NiCad batteries yield about 200-300 minutes of service, and performance
degrades at the end of battery life. Reset (RST) the battery counter in the
STATUS menu when you change the battery, so that you can estimate your elapsed
time. Use a camcorder battery with your cigarette lighter adapter to avoid
frequent battery changes. For a well tested camcorder battery see
Navtech GPS - Leatex Battery Kit, P/N
6240-3, $32.00 w/charger. This one seems a little better than the Multiplier
version because the battery harness is detachable from the battery and you can
charge the battery from your car cigarette light plug. It is also cheaper. URL:
