Key Features

• Antenna Calculator: Antenna dimensions based on frequency and wire type
• Construction Guides: Step-by-step instructions for various antenna types
• Technical Documentation: RF engineering principles and propagation basics

Project Purpose

Simplify antenna design while promoting understanding of RF concepts for ham radio, emergency communications, and experimental setups.

What You Can Do

• Grow the Farm: Buy, breed, and sell hedgehogs
• Keep Them Fed: Buy food and upgrade food storage
