These stand-off insulators are made for indoor use. They are made of plastic material. The flange has three slotted holes permitting to align the insulator’s cap screw clamping to the direction of the antenna feed line. The cap screw clamping can take copper tubes up to 8 mm diameter. Due to their mechanical properties and the plastic material made of, the stand-off insulators type ST are virtually break-proof. • Easy mounting • No broken ceramics • No maintenance Specification Height Slotted holes Width of cap screw clamping Mounting flange and thermoplastics Cap screw clamping Shaft polyester Max. RF operating voltage ST 300: 20 kV ST 500: 50 kV Tightening torque for max. 1.2 Nm fixing screws Designation Order-Code STA = Rod Antenna K = Tilt SSB = internal feeding NDB = Non Directional Radio Beacon E = Receiving Rod Antenna TR = reinforced SSB/E = external feeding EAU = Transformer SE = Transmit Antenna PM/M = dark grey (similar to RAL 7000)

RH insulators are made of plastic bars with rectangular cross sections of 40 x 15 mm. They have 8.5 mm bore holes on both ends in order to take up standard 5/16“ shackles. The permissible stress effect on these insulators is max. 400 daN at 23° C. RH insulators are resistant to all marine environment, especially to mention the extreme resistance to tension crack. Even under tropical temperatures the resistance against chemicals includes inorganic acids up to a concentration of 20 % alkali, aqueous solutions of inorganic salts, organic acids as well as alcohols, aldehyde, ketone groups,...

The lead-through insulator, series P, is especially designed for antenna installations on board of seagoing vessels. Insulation characteristics are at an optimum even under severe environmental conditions. Shipbuilding problems with regard to steel or light metal super-structures will not be encountered as the fastening flange of the insulator is made of thermoplastic material. Specification Insulator Lead-through axle Recommended mounting Antenna connection Transmitter connection Maximum RF operating voltage Dielectric constant Tangens delta Temperature stability water absorption Surface...

This lead-in insulator has been carefully designed to meet severe environmental conditions as one will find on board of seagoing vessels. The P 502 is made of high quality plastic material with outstanding electrical data over a wide frequency range (ceramics change their electrical data due to the applied frequency). The insulating material is UV-resistant, it has null water absorption, and its surface may be damaged (e. g. scratches) without any reduction of the very high insulation value. Special features have been integrated into the design to prevent arcing to ground potential and to...
