What is the difference between the Standard Horizon HX210 and HX40 handheld radios?
Both the HX210 and HX40 are analog VHF handheld radios with 6 W output, 1,065 channels, and IPX7 waterproof ratings. The HX210 has a Li-Ion battery providing approximately 10 hours of operation, while the HX40 uses a Li-Polymer battery with similar runtime. The HX40 includes a rapid charger and is backed by a 3-year waterproof warranty. The HX210 receives weather channels and FM broadcast (76–108 MHz). Both feature alphanumeric displays and VOX. Selection depends on battery preference and warranty requirements.
What are the specifications of the Standard Horizon 220SW and 240SW horn speakers?
The 220SW is a powered horn speaker with 4 ohm impedance, 8 inches overall width, and 10 inches overall height. The 240SW is a passive horn speaker with 4 ohm impedance, 9 inches overall width, and 7 inches overall height. Both are intended for public address and alarm systems in industrial and marine environments. The 220SW requires an external power source, while the 240SW is driven directly by an audio amplifier. Impedance matching is important for proper operation.
