Proxicast Coaxial Lightning Arrester/Suppressor with 75 Ohm F Female Connectors - Pro-Grade Coax Cable Surge Protector for Television (TV) / Satellite Dish Antennas & Cable Internet Use (ANT-271-002)

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!

So far so good. Checked inside to make sure everything was in place and not lodged in a corner. Install waz a breeze and total time to install them into my pre existing hook up along with running the grounds to the outlets ground took about 40 minutes max including finding tools. Shouldnt be hard as long as you look up your connector ends on your cables to make sure everything will hook up correctly. 1 being end type, being the tiny tiny SMA or F type or Standard coax or that HUGE connection called N type. 2 being the Male or Female hookup you will need or maybe a conversation end separately to be able to hook it up. Once your locked in on what you need its easy from there on out, couple or pliars and flat head screw driver making sure not to overtighten the ground screw.

Product is well made and hopefully I'll never need to use it. Installation was easy after trimming the center copper wire of the antennae cable that I attached to it (the coax cable was left with the center wire too long making it difficult to attach to the device).

This arrester is well-made and easy to install. They are just what I need to prevent lightning strikes from damaging my radio equipment.

Just ordered and installed, has some weight to it and appears to be well made, came well packaged and delivered promptly. End connection were well protected and has a good ground connection.

This device is solidly built, sleek, cold aluminum and the coax cords fit perfectly. We recently had a lightning storm and this along with a protected power adapter, the internet router was safe and sound. Only downside is that this will cause interference in the audio of landline telephones connected to the wifi router for use with VoIP calling.

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.

We recently went back to owning our cable modem/Router after renting a modem/router for several years. But we were worried that a lightning strike could fry our modem/router like it did before we went to renting. SO a quick search on Amazon led us to this Lighting Arrester. It's size makes it unobstructive in our cable box. And for around $20, it both a great value and a good investment in protecting our internet tech. We'll wait and see how well it protects against lightning strikes when the next storms happen.

Easy to install, hopefully it works as advertised if my antenna is ever hit

Did not fit my standard RG-6 Coaxial cable. The center conductor of the coaxial cable is to thick to fit into the adapter. I checked the diameter of the coaxial center conductor with a micrometer and it was within the specs for a RG-6 cable. Apparently I read there that not all of these central conductor cables are solid copper. Some are steel with copper coating and they have a much smaller diameter. It could be that this adapter is meant for that type of cable???
