ALL TIPS 2026 QUESTIONS AND ANSWERS SURE

✔✔Cold Weather Environment - ✔✔Whenever possible, tactical radios for tactical
operations in cold weather areas should be installed in vehicles to reduce the problem
of transportation and shelter for operators. This will also help solve some of the
grounding and antenna installation problems caused by the climate. Because of
permafrost and deep snow, it is difficult to establish good electrical grounding in
extremely cold areas. The conductivity of frozen ground is often too low to provide good
ground wave propagation.
-To improve ground wave operation, use a counterpoise to offset the degrading effects
of poor electrical ground conductivity.
-Remember to install a counterpoise high enough above the ground so that it will not be
covered by snow.
-Mast sections and antenna cables must be handled carefully since they become brittle
in very low temperatures.
-Whenever possible, antenna cables should be constructed overhead to prevent
damage from heavy snow and frost.
✔✔Mountainous Areas - ✔✔Operations of tactical radios in mountainous areas have
many of the same problems as northern or cold weather areas. However, the
,mountainous terrain makes the selection of transmission sites a critical task. The terrain
restrictions encountered frequently make radio relay stations necessary for good
communications. Because of terrain obstacles, tactical radio transmissions will
frequently have to be by line of sight. Also, the ground in mountainous areas is often a
poor electrical conductor.
-A complete antenna system, such as a dipole or ground-plane antenna with a
counterpoise, should be used.
-The maintenance procedures required in mountainous areas are very often the same
as maintenance in northern or cold weather areas.
-The varied or seasonal temperature and climatic conditions in mountainous areas
make flexible maintenance planning a necessity.
✔✔Urbanized Areas - ✔✔Tactical radio communications in urbanized terrain poses
special problems. Some problems are similar to those encountered in mountainous
areas:
-Obstacles blocking transmission paths
-Poor electrical conductivity because of pavement surfaces
-Commercial power line interference
VHF radios are not as effective in urbanized terrain as they are in some other areas.
The power output and operating frequencies of these VHF radios require a line of sight
between antennas. Line of sight at street level is not always possible in built-up areas.
To provide cover and concealment in urban areas, park radio-equipped vehicles around
or in buildings, dismount radio equipment and install it inside buildings, and place
generators against buildings or under sheds to decrease noise and provide
concealment.
✔✔TRANSMISSION SECURITY - ✔✔Transmission security is the component of
communications security that results from all measures designed to protect
transmissions from interception and exploitation by means other than cryptanalysis. The
enemy hopes to learn essential elements of friendly information (EEFI). Critical
information that must be protected can be remembered by the key words SELDOM UP.
Each letter of SELDOM UP indicates a class of information as follows:
Strength—number of personnel, size of unit
Equipment—type, quantity, condition
Logistics—procedure for resupply, depots
Disposition—where, what positions, map coordinates
, Organization—how, what, chain of command, force's structure
Movement and morale—where, how, when, good or bad
Units—type, designation
Personalities—who, where
✔✔BASIC TRANSMISSION SECURITY MEASURES - ✔✔Strict radio discipline and
adherence to authorized procedures are key to ensuring transmission security over
tactical radio networks. SINCGARS radios should be operated in a frequency hopping
mode to provide maximum protection against enemy electronic warfare capabilities.
Other transmission security measures include:
Well-trained operators thoroughly familiar with proper communications procedures and
equipment operation
Avoidance of unauthorized transmission and testing and maximum use of data networks
to minimize transmission time and opportunity for enemy direction finding
Use of transmitter, antenna, and power combinations that produce minimum wave
propagation and emission intensity consistent with reliable communications
Strict adherence to authorized frequencies
Use of authentication systems to protect against imitative deception on non-secure nets
Use of changing call signs and frequencies on non-secure nets
Use of communications means that do not radiate in the electromagnetic spectrum such
as messengers, visual and sound signaling, and local wire loops
