Is it the practical upgrade your handheld kit needs?

⚡ At a Glance
  • Signal Performance: Operates at 27MHz with VSWR under 1.5 and gain over 1.8dBi for improved reception
  • Best for: Outdoor enthusiasts and CB hobbyists needing extended handheld range
  • Not ideal for: Users who require integrated hands-free or multi-band operation

Telescopic antenna extends from 9.2 inches to 51.5 inches and uses an SMA-Female connector. VSWR below 1.5, gain above 1.8dBi and up to 20W power handling support stable handheld transmissions.


Longer range and clearer reception - thanks to extendable 9.2 to 51.5-inch telescopic length

Telescoping increases effective antenna length at 27MHz, altering resonance and improving radiating efficiency across CB channels. Greater physical length helps with line-of-sight pickup and transmission reach.

Longer contacts become possible when operating from campsites or vehicles, with noticeably fewer dropouts on distant stations.

Stable RF matching - with VSWR under 1.5 and gain over 1.8dBi

A VSWR below 1.5 indicates low reflected power and efficient transfer from transmitter to antenna, while measured gain improves signal strength on transmit and receive. Rated support for up to 20W keeps handheld output within safe limits.

Reliable power transfer reduces retuning needs and helps maintain consistent communications during extended use.

Portable, robust construction - with lightweight 0.08kg metal build and SMA-Female connector

Lightweight metal construction balances durability with minimal mass, keeping the antenna resilient to outdoor handling. Standard SMA-Female threading matches many handheld radios, though some sets may require an adapter.

Easy to carry on hikes or off-road trips, and quick to attach to compatible radios for field use.
