Coax cable question

[TheMan419]

As many of us are rural getting good high speed Internet is an issue.

I have an account with ubifi a cellular internet provider.

In an effort to get better performance I have ordered an external antenna for the modem/router.

I also ordered a length of ultra low loss coax.

My dumb question of the day.... can I just cut it and use the same ends and connectors and crimping tool for the coax that carries my satellite tv signal?

This is the cable on order. The 50 foot length should be well more than sufficient. I also figure shortening the length of the cable would be good too.

It says it has type N connectors. Here's a link to the same brand connectors too:

You will have to use the same type coax fitting that the external antenna and modem input jack use.

keep the modem with the router, and just use a roll of cat 5, why take the db loss?

then get something like this (currently on sale) to get the wifi into the house

Those extenders are absolute junk and also have nothing to do with what he is trying to do.

i know exactly what he is trying to do, and those extenders work well when having normal expectations.

He is trying to improve his cellular signal, that extender does nothing of the sort and yes they are junk and they also use bandwidth off of your wifi network to communicate back to the modem. His problem is not wifi but his problem is the cellular signal to the modem. If your wifi coverage is sub par then get a mesh system.

yes he is trying to increase cellular signal by using coax to extend the router i assume back somewhere in the house, coax has a db loss. if he keeps the antenna connection short and keeps the modem close, this db loss will be reduced. if the router he is using is his main wifi, then he might not get signal in the rest of the house, thus the point of the repeater.

repeaters work fine with low bandwidth applications, considering its cellular, its a none issue. and if the bandwidth usage is so HIGH, then he can get a dual band unit and remove the penalty.

There are huge losses at those frequencies in coax. It has to be special teflon stuff, with the right connectors. Even Telcos are putting their transcievers atop their towers to avoid the losses.

The OP states he is using the Coax to connect an External Antenna.... not to move the router to a different location.

Ok, it's not a dumb question... a couple of things:

Your crimper might work if it can do "Type N" connectors; many cable & satellite systems use "Type F" connectors on RG6 Coax which is a 75 Ohm system. If your crimper / compression tool does ONLY "Type F" then it will NOT work.

Also make sure you check your modem/router to see if it is 50 Ohm or 75 Ohm... you want all the other components (antenna, coax cable, connectors, etc) to match that Ohm rating. So if the modem/router is 50 Ohm use all 50 Ohm components.

You don't want to mix & match 50 Ohm & 75 Ohm components in the same system if possible. Mismatching 50 and 75 Ohm components in a system creates standing waves; which can relate to approx 5% of the signal being lost every time it is done.
