Our take on the Wilson 305-4FD 4' Flex Black Fiberglass Antenna

The Wilson 305-4FD is a 4-foot CB antenna built on a flexible black fiberglass whip with a tunable tip. The fiberglass shaft flexes under low branches and in wind where a rigid stainless whip would bend or snap, and the tunable tip lets you trim SWR to your specific mount and vehicle. It is a plain 4-foot antenna without the center-load coil of Wilson's trucker-style models, so it suits everyday mobile CB use rather than maximum range. Buyers pick it for durability and simple setup over raw gain.

Best forDrivers who hit low branches, garages or car washesOff-road and trail use where the whip takes hitsSimple mobile CB setups with a tunable match

Questions and answers

How does the tunable tip work?
You trim small amounts from the tip to bring SWR down on your setup. Cut a little at a time and recheck with an SWR meter, since you cannot add length back.
Is a 4-foot fiberglass antenna good for a CB?
It is a solid everyday choice. The fiberglass whip survives hits that bend metal whips, but a longer antenna generally gives more range on flat ground.
Does it need a ground plane?
Yes. Like any CB antenna it needs a proper mount and ground, such as a metal body panel or a mirror mount with a good ground connection.
What is in the box?
The antenna itself. A mount, coax and connector are not included and must be matched to your vehicle.
How does it compare with Wilson's center-load antennas?
Those use a coil for more gain and longer reach. This one trades some range for a simple, flexible whip that takes abuse.
