Part 15 The photo to the below displays a wide Variety of helices both encapsulated and unencapsulated. The brackets are used with the encapsulated version. Also included is a halfwave dipole for the master or control unit. These antennas are all for the 904 - 928 MHZ frequency band. At 900 MHZ, your circuit board acts as a groundplane to a helical, for example; but since every circuit board is different, the helical antenna must be properly tuned to work with your circuit board. This service we provide and shows up in extra range on your equipment. By careful Applications Engineering service, we can save you a lot of time and provide you with the best antenna for your application. These helices are made of heavy beryllium-copper covered with a thick silver plate. They provide a again of -1 to -2 Dbd over the entire band; same as 0 to +1 Dbi. The shrouds are made of a heavy but resilient plastic to provide shock relief when dropped.
