I see similar looking antennas online that say for 600 MHz to 2700 MHz, is a wider frequency spectrum better? Antennas with a focused spectrum will have better performance on that band segment vs antennas with very wide spectrum. We generally do not recommend wide spectrum antennas except as a tool for frequency testing. This antenna has a frequency range of just 902-928 MHz to give you maximum performance.
