A random wire is exactly that—a piece of wire that’s as long as you can possibly make it. One end of the wire attaches to a tree, pole or other support, preferably at a high point. The other end connects to the random-wire connector on a suitable antenna tuner. You apply a little RF and adjust the antenna tuner to achieve the lowest SWR.
Houses with antennas erected on their roofs were becoming a thing of the past. However, in the pursuit of eliminating unnecessary expenses, many people are now opting to cancel cable and satellite subscriptions, choosing to revert back to b

Adjacent to it are two SMA-antenna jacks. Jack ANT A is a 50 Ohm antenna input and covers 1 kHz -2 GHz. The ANT B (Bias-T) has the same properties, but additionally you can power active antennas with 4,7 V and 100 m Ah. Adding some coax between antenna-end and SDR might change the impedance that your SDR sees, and also change the frequency spans where the antenna is decently matched (and poorly matched). Coax will likely add some small signal loss too. For casual listening, throw up a good long wire, whose end comes conveniently-close to your SDR, and a short First off I will say I am no HAM operator but soon I hope to start down the slippery slope in another expensive hobby.

The wire antenna has a vertical run of about 30 feet then angles back down, approximately 34-40 feet to an anchor point. The first 20 feet is galvanized fence post. The last portion is PVC. The wire has a few turns around the galvanized pipe and PVC. The wire is clipped to the center threaded pole of the RTL-SDR magnetic base antenna. I was tired of the noise levels using verticals in my bedroom so I made a loop antenna out of 19mm copper pipe. The reception on shortwave is just stunning 2017-01-14 · I tried some experiments today with along wire antenna for the SDRplay.
I am about to string up a new long or random wire for my SDR and SW listening and looking for feedback on the length and positioning of the wire. My yard is small with no trees, but I can run the wire about 30 feet up then slope it down and run it anywhere throughout the yard. My yard is enclosed with a cinder block wall approximately 9 feet tall.

They can come close to half wave antennas in efficiency, although efficiency decreases as they are made very long or installed closer to earth. Like every antenna that exists, random or long wires have advantages and disadvantages. Adding some coax between antenna-end and SDR might change the impedance that your SDR sees, and also change the frequency spans where the antenna is decently matched (and poorly matched).

I have a NooElec Ham-it-up shortwave SDR receiver, and the associated 1:9 balun (with SMA connector on one side, 2 wire connectors on the other, for antenna and grounding wires). I want to connect a long wire antenna to the balun, to get broadband omni-directional shortwave reception. The SDR only has coaxial connectors, no direct wire connectors.
