Review: sheer weight indicates its build Quality ! - Can't rate it for "post strike" performance :^) ...but its sheer weight indicates its Quality and metal alloy construction
Review: Easy to install protection for coax connected electronics - This is a professional lightning arrester which is easy to install and has replaceable gas tubes so if in blows to protect the equipment, it can be put back into service with a new tube. The only problem I had was not with the product but with big A. Ordered the correct product and was sent the wrong one not once, but twice! Resorted to communicating directly with Proxicast who took back the incorrect item and sent the correct one. Tried to tell big A what the problem was but it didn't work. 5/1/2024 Update: Received the correct unit from Proxicast which was nice! Out of curiosity, I opened the port where the replaceable gas tube is located. When I did, it looked like there was no tube in the unit. Contacted Proxicast to let them know along with a picture of the missing tube. Right away, they apologized, said they would look into the problem, and sent some replacement tubes right away. After examining the picture I sent, they determined that the gas tube had actually fallen inside the unit so it was not missing after all. Since I didn't know what I was looking for and saw the empty hole, I assumed it was missing. I was able to retrieve the tube (not very easy) and now I know what can happen if you are not careful how you open it up. I have since suggested possibly some kind of plastic insert to keep it from falling into the unit or a "read me first" to warn of the possibility of the tube falling inside the unit if not opened carefully. Though I have offered to return the replacements, Proxicast has said I could keep them. This is -top notch- customer service which is very refreshing to find in a company where many would have ignored the problem all together. The take: If you need to remove the gas tube from the unit, place the unit on a flat surface with the port facing up and be aware that it could possibly fall inside the unit. This is a vendor you can trust that supplies a very good product and will respond to you if you have any problems. Buy this product if you need a good lightning arrester for your satellite cable feed.

### ⭐⭐⭐⭐⭐ Well made, beautiful construction.
*by R***Y on August 27, 2025*

This lightning arrestor is well made but is limited to about 350W SSB. Above that and it will conduct. The GDT that comes with the arrester is rated at 230V. To use this product with high power the GDT should be changed to a higher voltage. A 350 or 400V GDT will work to >1KW. The cover for THE GDT does not have an O ring so a piece of rubber tape should be placed over the opening to waterproof it. This is an excellent lightning arrester at a bargain price!
