Antenna stats

Purpose / Цель

English

This repository is supposed to consist of helpful, but not exhaustive antenna measurements.

Giving it's homemade nature, you shouldn't rely on it as a trustworthy source.

You can contribute to it by opening a Pull Request with your own measuremens. Here are some guidelines and instructions.

Russian

Этот репозиторий предназначен для сбора полезных, но не исчерпывающих измерений антенн.

Учитывая его кустарную природу, вам не стоит полагаться на него как на надежный источник.

Вы можете внести свой вклад, открыв Pull Request с вашими собственными измерениями. Вот некоторые рекомендации и инструкции.
