Norseman Aerial Rigging Insulators
For converting high tensile yacht rigging into antennae for transmission and
reception, Norseman Insulators provide a completely secure method of converting
yacht backstays into aerials. They have been approved by Lloyd's for many
years and the Norseman Insulator is recommended by leading marine electronic
distributors.
Insulators are manufactured from marine stainless steel to specification 316
Stainless Steel for the end fittings, an approved insulant, and anodised high
strength aluminium. Fully tested in an approved environmental laboratory,
electrical performance was found satisfactory after exposure to salt spray and
to 95% humidity at 35°C for four periods of seven days.
