SIRIO THUNDER 27 Base antenna CB 27 Mhz length 96 cm 1/4 wave

THUNDER-27

The SIRIO THUNDER 27 is a base CB antenna designed specifically to operate on the 27 MHz (CB) band, manufactured in black PVC to be discreet and suitable in places with space limitations, such as balconies, windows or roofs. With a length of only 96 cm, this 1/4 wave antenna offers a compact and aesthetic design, ideal for those looking for a discreet installation without compromising performance.

It operates in the 26-28 MHz range, efficiently covering the 27 MHz band, making it perfect for CB communications. The antenna offers a gain of 2.15 dBi, providing an improvement in signal transmission and reception compared to other antennas of similar size.

To optimize performance, it is recommended to use RG 58 cable with specific lengths that allow for better efficiency in signal transmission. The recommended measurements are:

2.73 m
5.46 m
8.48 m
12.34 m
17.98 m
23.77 m

These lengths help to minimize signal loss and ensure a good adaptation of the antenna to the radio system, maximizing its efficiency.

This antenna is an excellent choice for those looking for a discreet yet efficient solution for their CB band communications, especially in tight spaces.
