The antenna has a regulated gain in the operating frequency range. It is recommended for the study of electromagnetic environment in a set with a spectrum analyzer. The antenna comes with a 30cm SMA RG316 Cable for connecting it to a spectrum analyzer or other receiving device. Directional passive logoperiodic measuring antenna HT666 with gain up to 6 dB. Designed for radio frequency measurements (field strength measurements and amplitude direction finding of electromagnetic radiation sources) in the frequency range from 600 to 6000 MHz. The wide operating range of the antenna allows to measure the signal level of all common technologies and standards 2G (EDGE, GPRS on frequencies GSM900, GSM 1800) 3G (UMTS 900, UMTS 2100) 4G (LTE 800, LTE 1800, LTE 2600), YOTA WI-FI 2400 (IEEE 802.11b, g, n) Applications The following can be accomplished using the measurement antenna: Analyze the radio frequency environment; Aim the antenna at the base station; detect of signal or interference; analyze the operation parameters of amplifiers (repeaters).
