We also provide the E22-170M30S module for niche applications requiring operation in the 170 MHz VHF band. This imported module is designed for basic, long-range transmission where penetrating dense obstacles is the main goal. While its low-frequency signal offers good penetration, the module is entirely restricted to the 170 MHz band, offering no flexibility or protection against signal interference. This module is an option for specific, non-critical projects, such as agricultural monitoring, that do not require the security or versatility of a multi-band system.
E22-170M30S
-
Single-Band Operation: Fixed to the 170 MHz VHF band, it cannot adapt to RF noise or switch to a clearer frequency.
-
Specialized Penetration: Best suited for rural or obstruction-heavy environments, but lacks versatility for mobile or dynamic applications.
-
Standard Power Output: Includes a 1-watt (30 dBm) amplifier for standard long-range performance within its narrow operational band.
-
Imported Components: This product is manufactured in China. We do not recommend this module for critical infrastructure or for integration into the American defense supply chain due to its foreign origin.
-
No Cross-Band Capability: Operates in isolation and is incompatible with common ISM bands like 868 MHz or 915 MHz without a separate gateway solution.
