GME AE4001 UHF CB Flexible Antenna 150mm 2.1dBi Stainless Steel

PRODUCT OVERVIEW

The GME AE4001 is a compact 150mm flexible stainless steel UHF CB antenna designed for applications where space is limited. With 2.1dBi unity gain and a durable chrome ferrule, it delivers reliable performance in demanding environments.

KEY FEATURES

• 150mm flexible stainless steel whip for compact installations
• 2.1dBi unity gain for broad signal pattern and consistent coverage
• Chrome ferrule for strength and corrosion resistance
• Standard 5/16" thread, interchangeable with a wide range of bases
• Suitable for use in built-up, rugged or obstructed terrain

DBI GAIN EXPLAINED

Antenna gain, measured in dBi, indicates how effectively an antenna focuses radio frequency energy in a particular pattern. A 2.1dBi unity gain antenna like the AE4001 outputs a signal at the same level as the input, spreading coverage over a wide pattern. This makes it less affected by obstacles such as buildings, trees, and rugged terrain compared with higher gain antennas that focus the signal more narrowly.

APPLICATION GUIDELINES

• Unity gain (2.1dBi): Broad coverage pattern, ideal for hilly, mountainous, or heavily obstructed areas.
• Medium gain (approx. 5.1–6.6dBi): Balanced option for mixed suburban and country use.
• High gain (approx. 8.1dBi): Narrow, long-range pattern suited to flat, open terrain.

Choosing the correct gain profile based on where you primarily drive helps maximise the performance of your UHF CB system.
