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

Product was as ordered and delivered on time.

Looks good! Got it hooked up, and wrapped connections with rubber water proof tape. Time will tell if it is effective. Hoping I never have to find out if it did/didnt work.

Lightning Happens. Youll wish you had one of these, properly-grounded, on you antenna lead-in.

looks good, I hope I will never need it.

So far they havent been tripped by lightening or anything but I have them installed on two HAM antennas attached to my minivan. My SWR remains below 1.4 and there is no perceivable interference. The grounding screw makes it easier to ground too.

I liked it for the size.

The name of the product may be overly ambitious. It probably cant stop a lightning strike from doing damage. It can, however, drain off the high impulse voltages produced by nearby lightning. It should be placed close to a ground rod, connected to the rod by heavy-gauge copper wire. Cut the coax and put a PL-259 connector on each side. Screw them onto the SO-239s on the lightning arrestor. Installation finished. You can feel a little more comfortable, but still remove the antenna cable from the radio during thunderstorms.

For now , I am using this with a end fed SWL antenna. It is my hope to obtain a Ham radio license in the future and with that in mind , my purchase of this device will work with any modest transceiver.

I hope I never have to test it to see how good it really works

No lightening yet but seems ok
