The Aerial Bases (VHFB & MVHFB) are injection moulded from high impact nylon which gives UV protection and long service life. The Aerial Whip Adaptor (AW12) is machined from brass with a nickel plated finish, while the high tensile Stainless Steel Whips (WO9) are machine ground to provide flexibility, and are capped with a neat machined tip.
Each 1/4 wave model is also available in a black finish.
The whip length provided for the VHF model is 980mm and 200mm for UHF. Unity gain with an omnidirectional pattern are typical features of a ¼ wave antenna.
