Proxicast ProGrade 230V Coaxial Lightning Arrester - 75 Ohm F-Female/Female

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.

Sturdy construction. Confirmed it works with MoCa 2.5 without any connection issues. I like that it has a replaceable discharge tube so the entire unit doesn't need to be discarded.

At first I was not able to get a RG6 cable to connect to it. After an email with their tech support they said that it has to have the inner conductor of the coax screwed into the arrestor rather than forced by pushing. So take the coax in your left hand put the center conductor of the coax in the hole of the arrestor then turn the arrestor with your right hand and screw it onto the coax because it is an intentional tight fit. Once I got it together there was no signal loss.

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.

In theory, cablemodem line should be properly protected by the cable company at point of entry. Except, in my complex, it runs quite a bit of distance in a crawl space before reaching me -- so I am worried about nearby ground strikes that may induce a surge into that stretch. I didn't trust a no-name suppressor and considered buying a Phaser unit -- which is 9.5x the price of this! So I was happy to find this unit. After some testing, I noticed no loss in speed with cablemodem. From the specs, DOCSIS 4.0 should be fine too. Great unit. And available with every possible F connector combination so I didn't need need to add any extra coax segments to install the suppressor.

Failed at its Job. Now i have lost two cable modems, one with out a surge protector and and one with this particular surge protector. If you screw the little screw down too far it will be trapped inside forever, lol. I bought extra fuses and they all look the same so my guess is that the fuse did not absorb the surge. If you look inside of the barrel you can see a small rod that connects both ends and a seat for the fuse so i dont understand how the surge is going to go thru the fuse when it can clearly bypass it.

Great surge protector. Worked great on the network

Useless until I can find the gas tube that was supposed to be inside, trying to contact manufacturer as to why it wasn't included with the unit. Update.. gas tube was lodged inside and not visible, appeared to be missing but was not.

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???
