Coax Calculator

About this app

An easy tool for the technician for calculating with coaxial cable.
This tool is only for 75ohm cable networks.

This tool is usable for:
Coax attenuation calculations for:
• Coax 1.5
• Coax 3
• Coax 6
• Coax 9
• Coax 12
• Coax 18
• RG6
• RG11
• RG59

Level calculation on the AOP:
• The best tap is calculated from the length and type of the coax.
• The calculation uses a MT12 tap. The level on the AOP should be minimal 62 and maximum 75dBuV.

Manual:
• All buttons are always fixed at startup.
• Any change will be calculated immediately.
• For convenience, you can use the sliders, but you can also use a keyboard.
• Max. length and frequency adjustable in settings menu.

Furthermore, these extra tools have been added to this app:
• Calculate return loss.
Calculate reflection damping for measuring equipment without reflection measurement.
• Extrapolating measurements.
Guess a 3rd measurement when two measurements are known.
• Unit conversion.
With this you can, for example, convert dBmV to various other units.

Note:
• In practice, signal attenuation can be different than calculated here. This sometimes occurs because of aging of the cable, or by the manufacturer of the cable.

• Sometimes a different tap connections is being used by a designer then what is calculated here.

Ratings and reviews

Rather poor does not have information for most common 50 Ohm coaxial cables. So pretty much worthless for myself and many other Amateur Radio Operators. Also difficult to set UHF frequencies. Needs a ton of work.

Fantastic. Does what it says, and quickly. I love it. No fluff if you know what I mean. Great to have such a good programmer who takes a professional's time into account. I love you. OK, maybe love is too strong of a word. I like you a little less than bacon 🥓!

This app was great before, you have absolutely ruined it, why?

What's new

This release has many improvements.

What's new in this app:
- Calculate return loss.
- Extrapolating measurements.
- Unit conversion.

What are the improvements in this app:

- The startup icon has changed.
- Migration to AndroidX, this makes the app future-proof.
- The changes are minimal, but the app has a different appearance.
- Minor errors have been corrected.

More big stuff to come, stay tuned!
