Antenna Tool

A tool to help ham radio, CB, and other radio users to create antennas of various types. Calculations available for dipole, vertical (1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, and full wave), inverted vee, quad loop, delta loop, and yagi. Simply enter the frequency, select the antenna type, and all necessary calculations are displayed.

Excellent app for quick measurements. But would be nice to have a diagram of each antenna type that is listed in the app.

Has the standard measurements of the antenna wrong. Has driven as shortest. However, in metric, it is correct.

First class App , very accurate, my own calculations prove its accuracy as very good. Now older and have a lazy brain. Just knocked up a 40m band loop and vertical before i had this app and it confirms my measurements as ok. Fed via a balum in my case.

Great app, UI is nice and easy to use. I don't agree with it having ads but I guess the creator needs money

Gave me wrong wavelength calculations for the frequencies that I was looking for not a very antenna friendly app as I see it I am a CB radio operator and the wavelength calculations that they gave me were off by about 9in

Wow. Great app

Awesome app, made useless by the crap GUI.

Nice app but hard to read due to colour of txt and background would be better with plain background.also increse number of elements for yagis

Most of us probably use wire with a plastic shield. In this case, I find the lengths of this tool should be reduced by .05 percent.

I don't mind ads, but flashing ads are irritating and distracting. Uninstalling.

Difficult to read the text against the exist background.

Black text on patches of white and blue is not necessarily easy to read.

Great app and very handy for all

Fantastic tool but very questionable adverts. Every advert I received wanted to infect my phone.

Dr. G. S. Dec 29, 2015

I could not figure out why the keyboard popped up when finished calculating an antenna. A save function would be useful.

A. G. u. Dec 31, 2016

There is no longwire stated, so useless for me.
