Why use an external antenna?
All stock rubber antennas on radios are poor radiators to begin with. When
using a portable inside a vehicle, it becomes very difficult for the radio
signal to penetrate inside the vehicle due to metal etc.
An outside antenna will allow all the signal to be radiated from outside
the vehicle,
and will raise the antenna a few feet higher, producing better range!
How much more range is a question often asked.
Typically you can almost double the distance you get with a standard 5
watt radio! Range is relative to your surrounding terrain, buildings, etc.
Most people notice a significant difference.
Other dealers try to sell me a 5 db or more DB gain
antenna,
why don't you recommend this?
High gain antennas have one problem.
The higher the gain you go, the more compressed the radiation pattern is
towards the horizon.
In a typical radio system you don't want a high gain antenna, you want a
lower gain antenna that will fill in the pattern closer to the horizon
which is where you are trying to talk.
High gain antennas can cause "multi-path" which is the signal arriving
from more than one source at a time,
and this can actually "cancel" the signal out that you're trying to
receive.
It also means that you could easily "over-shoot" where you're trying to
talk to!
We recommend 0-3 DB gain antennas for all systems, unless you're in the
middle of the desert with no obstructions.
Our antennas are rated over a radiator in free space,
which is a more industry accepted method resulting in no "marketing
hoopla"
Also another problem found in the industry is the higher the gain antenna
the longer it is....
and mechanical integrity becomes an important issue! |
