We do not declare any gain and electrical length for our CB mobile
antennas for the following reasons:
- ALL the CB mobile antennas shorter than 2.5m and with coil in the
bottom are a 1/4 wave (ALL types means: Antennas from SIRIO and from
Competitors)
- The maximum gain of these antennas type are equal to 1/4 wave
antenna and the max gain is 0dB refered to 1/4 wave antenna (0 dBd =
2.15 dBi) and if 2different models, also taken from competitors, have the same length
and construction it means the gain is IDENTICAL.
However, a lot of customers declare FALSE info (See example below)
They could declare that their CB mobile antennas have 5/8 wave lenght,
8 db gain and only 1.5m long ..... This is really ABSURD, because the
radiant part (only this part can capture and transmit the RF signals)
should be 6,9m long and not only 1.5m This is a PHISICAL LAW !! Most
of these declarations are written for commercial purposes but they are
completley FALSE !!
This is the reason why we prefer not declare rather to declare wrong !!

Kiekvienas vertinkite pagal save, bet as tikiu kad visos tos antenos kurios stovi ant musu masinu stogu ir prie kuriu rasoma kad 5/8 ir daugiau nei +3dBi yra tik mitas ir nedaugiau nei reklaminis triukas.
