If your TV picture displays herringbone patterns or your FM reception is overloaded with distortion, the signal may be too strong. These attenuators reduce the signal strength to correct these problems. They simply connect in-line with the aerial lead and feature a standard coax socket at one end and a standard coax plug at the other. They have bright aluminium alloy bodies and are suitable for VHF and UHF. They have low VSWR and are clearly marked. Two types available: 6dB or 12dB. Length 45mm (approx).
