Review on πŸ’‘ SMA Lightning Arrestor Surge Protector with Replaceable Gas Tube Element 90V – SMA Male to Female Connector, 0-6GHz by David Pearson

Revainrating 2 out of 5

Doesn't seem right?

Discharge tube is a 3 pin device and I think it should be a 2 pin device. A 3-terminal device expects the middle terminal to be grounded, and each end provides protection for it. This tube is rated at 90V when connected as such, but in this case the protection is continuous and it is not known if this device was intended to be used in this way. If it could work like that I would expect the breakdown voltage to be double that or 180V - not so good. I would prefer to use a 2-terminal device. Also, I don't know what the washing machine is for and where to put it. I'm assuming it goes between the cap and the GDT. If I can't find a suitable 2 terminal device I'll probably return it.

Pros
  • 2. SMA Lightning Arrestor Protects 50 ohm SMA cellphone amplifiers, GPS receivers, wireless video systems
Cons
  • Will not fit all
