User's Manual

The integrated antenna mount provides an industry standard TNC-female RF connector that is
compatible with a wide range of mobile whip antennas.
Battery Care
The ADL Vantage Battery/Charger kit (PN K01115) includes a 12-Volt, 8-AHr, deep-discharge,
lead-acid battery. This battery provides all-day operation for the radio and may be recharged
approximately 300 times over a period of 3 years.
To power the ADL Vantage with a user-supplied battery, select a deep-discharge battery with
a minimum capacity of 8 AHr. Batteries designed for automotive use can be used if necessary
but will be damaged by repetitive discharge/charge cycles and are therefore not
recommended.
Charging
The charger supplied with the ADL Vantage Battery/Charger kit (PN K01115) provides two-
stage charging and should be connected to the battery following every full day of operation
to assure good battery life and performance. The first stage quickly charges the battery to
capacity and the second stage trickle charges the battery to maintain a full charge.
It is important to periodically charge any battery that is stored for an extended length of time.
Storing batteries for an extended time in a discharged state will damage them. To recharge a
user-supplied battery, select a charger of appropriate type.
Tips and Techniques for Best Performance
Antenna
Antenna placement is critical for good performance. Range and coverage is directly
proportional to the height of the transmitting and receiving antennas in addition to antenna
gain. Where possible, select a reference station location that takes advantage of terrain to
get the transmitting antenna as high as possible.
Always use the telescoping antenna mast and raise the antenna as high as is practical and
safe given terrain and wind conditions.
Do not use a gained antenna if doing so increases the radio’s Effective Radiated Power
beyond the limit of your license.
Line Loss
Line loss, produced by RF or antenna cables that connect the radio and antenna, decreases
the output power (Wattage) transmitted by the antenna, thereby decreasing the signal’s
range. To minimize line loss, please check the loss-per-length of cable to be used. For every
