MFJ-270 Lightning Arrester DC-1GHz, UHF-F/F 400W by MFJ

I sure hope I never have to test this, meaning, I hope my antenna never gets hit by lightning. However, Im happy that I included it on my antenna setup, just the same. Ive had it inline to my antenna for a while now. It hasnt negatively affected performance of the antenna that Ive been able to detect. It didnt change the impedance or SWR either.

Have this mounted in a junction box near where my antenna coax enters the attic. Crimp connector for the ground wire was easy to use, even with just a pair of needle nose pliers at my disposal. Hope Ill never need to use this, but definitely feel a lot better just having it!

Have not had any problems TX or RX on 2 meters.

OMG, ANOTHER Marvel of modern science.

Product was as ordered and delivered on time.

Another nice quality product from MFJ!

I hope the MFJ-270 never gets to be tested. I am placing two of these for each antenna. One at the base of the antenna and another at the back of the house. Hope to cut down on EFI along the coax. Trying to cut down on noise returning to the Ham Shack.

I cannot attest to the ability of this product to protect against all surges, however, we have had some pretty severe storms and the radio is still operational. Also important is that Ive experienced no noticable insertion loss which was a concern. Ill definitely add more when additional antennas go up. The little bit of added peace of mind goes a long way.

used on my HAM radio antenna system

Looks nice.. But I hope it is something I will never need. Just a little peace of mind.
