📡 1PC GSM 3G Module Antenna 824-960M / 1710-2170Mhz CDMA WCDMA Aerial with SMA Male Connector, 5cm Length Review

I bought this antenna to set up an SDR radio to receive the local police with the P25. Lines for frequencies with activity. With this antenna, the waterfall display shows granularity with fuzzy lines for frequencies with activity and no signals are being received. I bought this to make SDR easier. The standard antenna has a cable on a nearby table. This antenna screws directly into the SDR for a cleaner installation. But it just doesn't work. I will return this antenna.

I used VNA to see how the performance looked. the reference impedance is 50 ohms) with the indicated ranges shown. The first graph covers the bands from 500MHz to 1300MHz with 800MHz, 854MHz and 960MHz markers. The second graph covers the bands from 1300 to 2500 MHz with markers at 1710, 2109 and 2170 MHz. As you can see, the performance is quite decent around 850MHz, with an RL of -20dB. At 800 MHz it only drops down to -10 dB, but at 960 MHz it drops quite sharply (-3 dB). Performance in the…

Good delivery time. Also very well tuned at 860 MHz. And works well on scanner in 800mhz system on sds100.
