Introducing the Dual 6540 1 kW 70 cm Band Pass Filter – the ultimate solution for enhancing your transmitting and receiving performance in the 430 – 440 MHz range. With its exceptional features and top-notch design, this filter is a must-have for any antenna setup.

Description

Introducing the Dual 6540 1 kW 70 cm Band Pass Filter – a high-performance solution for both transmitting and receiving applications. With its exceptional low insertion loss and superior design, this filter ensures optimal signal quality and protection for your communication system.

Designed to be used in line with the antenna, this band-pass filter effectively suppresses any harmonics from 70 cm up to an impressive 1 kW of power output. Whether you’re using it as a transmitting filter or a receiving filter, it guarantees reliable performance and enhanced signal clarity.

On the transmit side, this filter plays a crucial role in eliminating unwanted harmonics that may arise from your 70 cm up to 1 kW linear amplifiers. By effectively suppressing these harmonics, it enables seamless transmission and ensures compliance with industry standards.

On the receiving side, the Dual 6540 1 kW 70 cm Band Pass Filter serves as a vital component before your LNA (Low-Noise Amplifier). It acts as a robust shield, protecting your receiver’s performance from any interference caused by HF, FM 2 m, 220 MHz, or 23 cm strong stations. This ensures optimal reception quality and prevents any signal degradation.
