Most ham radio operators will build an antenna of some sort when they first start listening or transmitting, whether it’s a simple dipole, a beam antenna like a Yagi, or even just a random wire ...

I suppose someone could build a directional 75-300 Ohm balun, but I've never seen one. Put F-59 connectors on the end of your coax and a 75-300 Ohm on the far end.

LONDON — Two passive ICs from STMicroelectronics NV allow designers to connect an antenna to a Bluetooth transceiver using a single chip. The BAL-2593D5U and BAL-2690D3U are integrated baluns used to ...

[G3OJV] knows the pain of trying to operate a ham radio transmitter on a small lot. His recent video shows how to put up a workable basic HF antenna in a small backyard. The center of the system is a ...

Impedance mismatch in a circuit results in energy being reflected back to the source, reducing the amount of power available to the load and possibly causing damage to the power source. Matching the ...
