A very high quality 5/8 wave antenna with groundplanes. This is probably the best base antenna available.

Made from aluminium with Magnesium for better radio conductivity and maximum strength. This is certainly the strongest aluminium antenna available.

The large open coil prevents any build up of water or condensation and allows the antenna to handle high levels of RF power.

The top section is adjustable for swr, although in our experience there is usually no adjustment necessary.
