FT-720D Multi-Band Ham Radio Duplexer for High Power
✔️ VSWR under 1.2 across 1.5-150MHz and 400-460MHz, 1000W max

The FT-720D is a high-power, multi-band antenna duplexer designed to share a single feed between multiple amateur radio bands. It's commonly used in base stations and mobile setups to protect equipment while allowing simultaneous operation across HF and VHF ranges.

✅ Frequency range: 1.5-150MHz and 400-460MHz
✅ VSWR: less than 1.2 across the bands
✅ Max power handling: 1000W (1.6-30MHz), 400W (140-150MHz), 250W (400-460MHz)
✅ Connectors: 3x PL-259, UHF-Male

💡 What is a high-power ham radio duplexer used for in multi-band setups?

A handy explanation: It lets you share one antenna across bands while keeping transmitter and receiver paths isolated, which protects gear and reduces interference.

- Multi-band antenna sharing and path isolation - Protects transmitter/receiver gear during high-power operation - Improves signal integrity across HF and VHF ranges - Simplifies base-station and mobile installations✝️
