I've been lookin at lightening arrestors. I've seen prices ranging from $20 to $100, I'm wondering if anyone has any information on the differences. I found some from L-com that seem to be middle of the road regarding price, they are about $38 each.
I have a 2 meter Vertical and 2 coaxial fed dipoles that I'm looking to buy these arrestors for. These will be mounted in an enclosure on the outside of the house, well grounded etc. Any opinions/thoughts would be appreciated.

Alphadelta dipoles have it already at the feedpoint. Check however power handling. I would add a 1 mega ohm shunt resistor

Just place a shunt inductor with 7 turns of Teflon center conductor (RG-142) from the coax center conductor to coax ground. Use a clamp on RF coax bead for RG-8 coax for the ferrite core.

Ninety nine point three percent of lightning energy is below 1 MHz.99.93%. This will also kill P static.

Most lightning damage comes in to your ham shack via the home AC feed.

Poly-Phaser or Alpha-Delta.

Just check and make sure you don't get DC blocking if you need it for an external outside antenna switch like the Ameritron RCS-4

If you have deep pockets, the German HOFFI brand, sold by Array solutions, is top of the line, and the GDT's are field replaceable.

The shunt inductor across the feedpoint will also work good.  Yagi's with a helical hairpin, or beta match already do that....and DC grnd the center conductor.   Bonding the braid of the coax to the top of the tower..and also the bottom of the tower is good practise....as well as routing the coax down the inside of the tower.
