{"product_id":"aaronia-bicolog-30100-x-204-008","title":"Aaronia BicoLOG 30100 X","description":"\u003cp\u003eThe Aaronia BicoLOG 30100 X is an active biconical measurement antenna covering 30 MHz to 1 GHz, with 8 dBi to 41 dBi gain. It has a built-in preamplifier for weak signals. With an SMA (f) connector, a 1\/4\" tripod socket and a 350 x 160 x 140 mm body, it suits radiated emissions pre-compliance, interference searches and field measurements across 30 MHz to 1 GHz.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt-In Preamplifier for Low-Level Emissions\u003c\/h2\u003e\n\u003cp\u003eBiconical antennas have low gain at the bottom of their range, which is why the passive BicoLOG models show negative gain there. The BicoLOG 30100 X adds a built-in preamplifier, and Aaronia gives its gain as 8 dBi to 41 dBi across the range, so low-level emissions stand clear of the spectrum analyser's noise floor without an external preamplifier. The datasheet lists 104 calibration points in 5 MHz and 10 MHz steps.\u003c\/p\u003e\n\n\u003ch2\u003eCompact Size for Handheld and Mobile Use\u003c\/h2\u003e\n\u003cp\u003eAt 350 x 160 x 140 mm and 500 g, the antenna is small enough to hold by hand on Aaronia's pistol grip, which also makes quick changes of polarisation easy, or to mount on a tripod through the 1\/4\" socket. Aaronia describes the BicoLOG series for mobile and stationary use.\u003c\/p\u003e\n\n\u003ch2\u003eConnecting to Your Analyser\u003c\/h2\u003e\n\u003cp\u003eThe SMA (f) connector takes a standard SMA cable; Aaronia recommends its 1 m standard or 5 m and 10 m low-loss SMA cables, and offers an SMA to N adapter for analysers with an N input. Aaronia describes the BicoLOG series as ideal in combination with spectrum analysers. With the active models, the preamplifier at the antenna makes the cable loss less critical.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eFrequency range\u003c\/th\u003e\n\u003ctd\u003e30 MHz to 1 GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eDesign\u003c\/th\u003e\n\u003ctd\u003eActive biconical\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eGain\u003c\/th\u003e\n\u003ctd\u003e8 dBi to 41 dBi\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eCalibration points\u003c\/th\u003e\n\u003ctd\u003e104 (5 MHz and 10 MHz steps)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eNominal impedance\u003c\/th\u003e\n\u003ctd\u003e50 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eRF connector\u003c\/th\u003e\n\u003ctd\u003eSMA (f), or N with adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eTripod socket\u003c\/th\u003e\n\u003ctd\u003e1\/4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eDimensions (L x W x D)\u003c\/th\u003e\n\u003ctd\u003e350 x 160 x 140 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e500 g\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAaronia part number\u003c\/th\u003e\n\u003ctd\u003e204\/008\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eThe specified range is 30 MHz to 1 GHz.
