## What is Coax Line?

Simple and fast app that allow you to calculate the loss of your coax line. Select your coax from up to 80 differents type, line length, antenna gain, frequency, SWR and power; it will give you:
Matched Loss
SWR Loss
Total loss in db and watt
Power in antenna
System Power Out
System Efficency
Electrical Length

It also provides some helpful information on cable features, like:
Outer diameter
Bending radious
Velocity Factor
Impedence

Ideal for checking your coax line on the go, or improving an existing one.

If you need a specific cable or a new function, feel free to drop me a line via the "Contacts" page inside the App!
