Measuring Small Antennas
-
If you have a small PCB with a small antenna you can't use a thick cable and a large connector. Not only is this impractical (how to connect the connector?) but the metal bulk will also affect the antenna and grounding properties of your PCB. The measurement will be useless. MegiQ promotes the use of the small and popular UFL connector and its associated cables. The UFL socket fits on almost any PCB and it can be improvised on a board without a UFL footprint.

VHF Radio Direction Finding Antennas
Vector-Finder Series
-
The Vector-Finder Series of VHF direction finding antennas provide a compact, lightweight, active antenna, suitable for use in the field with handheld transceivers and scanning radios. The mechanical design allows the sense antennas to be folded back to provide a compact unit, easily stowed or transported in any vehicle. The system interfaces with any FM receiver or transceiver via the antenna jack and the earphone jack. Several different models are available to suit your pocketbook or unique field application, all of which operate on the phase shift technique. The VF-142Q models incorporate left-right indicators as well as an audible response from which the user can determine the true direction of the radio signal. The other types utilize the audible response generated by the equipment and heard on the user’s receiver or transceiver. All models operate from a 9-volt battery.

Antenna, Wideband Discone
EM-6115 | 10 KHz – 2 GHz
-
The EM-6115 is a broad band collinear array allowing very wide Omni-Directional frequency coverage in a single package. Below approximately 100 MHz, the EM-6115 acts as an active vertical rod which offers 10 to 12 dB Greater unsaturated instantaneous dynamic range than competitive antennas (overload field strength: 2 V/meter) which greatly reduces intermodulation generated signals in a typical read world RF environment. In the congested spectrum above 100 MHz the antenna is passive and contributes no intermodulation products so the overload point is determined solely by the receiving instrument. This immunity to overload can often make the difference between useful signal output and an indecipherable jumble of spurious products and is accomplished without compromising sensitivity. The antenna collapses for convenient storage and transport.

Real-time Web Log Analyzer
GoAccess
-
GoAccess is an open source real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly. The main idea behind GoAccess is being able to quickly analyze and view web server statistics in real time without needing to generate an HTML report (great if you want to do a quick analysis of your access log via SSH). Although it is possible to generate an HTML, JSON, CSV report, by default it outputs to a terminal. You can see it more of a monitor command tool than anything else. Or if you are simply concerned about third party analytics tools using JS trackers.
