Easy in the field

This app is very easy to use and very quick.

We enjoy using it in the field to make last-minute calculations to modify antennas and to update existing ones

I thought this would show me pictures, give me materials to use. I can do length calculations on my phones calculator.

Much Thanks

This app has been so useful to me for years now. .
It is easy to understand because the developers made the concepts visually clear!

No longer works with IOS 11

This used to be a great app. But it has not been updated in awhile. This version will not work with IOS 11 until updated. This has since been updated, it is once again a great app. Thanks so much

FAQ

What does HamAntCal do?

HamAntCal is a mobile application designed for amateur radio operators to calculate the starting lengths needed for constructing various types of antennas. It supports common antenna designs like dipoles, inverted vees, and verticals, and can also calculate specific fractional wave lengths.

What types of antennas can I calculate with this app?

The app allows you to calculate starting lengths for 'Dipole' antennas, 'Inverted Vee' antennas, and 'Vertical' antennas. It also features a dedicated page for calculating 1/8, 1/4, 1/2, 5/8, and 'Full Wave' lengths.

How does the Inverted Vee calculation work?

The Inverted Vee calculator includes a slider that allows you to adjust the angle of the wires from horizontal, starting at 45 degrees and going down to 20 degrees. As you adjust the angle, the calculator continuously re-calculates the required length, accounting for the change in wire angle.

Does the app provide exact antenna measurements?

No antenna calculator can provide exact results in every situation, as factors like wire type, height above ground, and nearby objects influence performance. The app provides starting lengths, and it is recommended to add extra wire and trim to the desired frequency using an antenna analyzer or SWR meter after installation.

What are the system requirements for HamAntCal?

This update requires iOS 8.2 and above. The app has been updated to 64-bit and is compatible with iPhone X. There is also an in-app purchase available to unlock additional features.
