[K5ACL], aka [SignalSearch], recently brought his active receive loop antenna in off the roof to give it a checkup and perform any necessary maintenance. While it was in the shack,he took the opportunity to discuss how well it would perform indoors. The verdict? Not ideal. He’d mount...
The MLA-30+ loop antenna is a popular broadband antenna. It is an effective antenna for short-wave listeners (SWL) and amateur radio enthusiasts (HAM) to receive medium-wave and short-wave in limited living areas. Frequency covers from 100KHz to 30 MHz. Excellent directionality can help redu...
Complex and dynamic control of radiated fields are advantageous for flexible radio systems, which naturally move, roll, bend, twist, deform, and vibrate. Practical challenges hinder the proliferation of these antenna arrays. This work shows how using rad
handhelds, so it is done via software. Both receive and transmit audio seem to be very nice. Menus are logical and I was quite fast familiar with the whole setup. TYT’s antenna could be a bit better but you can always replace it with “rat-tail antenna” as nagoya-701. First thing...
In order to ensure the reliability of the RF interface between the main feed network and the central electronic equipment, a 1:1 power bridge is used to synthesize the signal from 1:2 power splitter of transmit chain and 1:2 power splitter of receive chain while achieving two points intercon...
An active retrodirective antenna array is provisioned with a virtual beacon for use with uncooperative targets. An RF pilot signal is imposed onto an optical carrier beam and direct
