sp e - 1 3 - 8 - 0 16 / a / ez page 2 of 10 1. introduc t ion the tg. 1 9 quad - band gsm - dcs - pcs - cdma - gprs - edge 824mhz to 1990mhz monopole helical antenna is a quality robust antenna with high gain in a small form factor. its tiny size allows it to be used inside as well as outside product housings. conne ction i s made via fixed right angle sma(m) connector with a hardened waterproof pu casing . care should be taken that the antenna is connected to the device main - board ground, through the mating connector grounding on the device main - board. for smaller ground - plane devices or for devices where a ground - connection to antenna is not possible we recommend the tg.10 or tg.30 dipole antennas which do not need to couple to ground.
