MFJ's Guardian AngelTM Lightning Surge Protector has an Ultra-fast gas discharge tube that safely shunts up to 5000 amps of peak impulse current harmlessly to an independent ground. SWR less than 1.1:1.

Less than 0.1 dB loss. Use up to 1000 MHz. MFJ-272MF handles 1.5 kW PEP. MFJ-272MF does not protect against a direct lightning hit.

You can also order the MFJ-97H, which is a replacement gas discharge tube for your MFJ-272MF.
