I've been curious about those SDR Radios. So I went ahead and ordered one, and an up-converter so I can try to listen to some shortwave. I also put up a lon

I would have to try a a larger gauge wire and more of it. since I,bought my grundig,from amazon ,on here its a,new 750 satiliit,the antenna with the 750,is a very good antenna,but this Usmile external,long wire is a,world of difference better,in receving sw.and ham bands too,and aircraft also,i recommend this ,long wire antenna to any one who may have a, sw radio be it a, Grundig, 750,-800 milinium or what you may have ive used it as a sloper antenna High impedance wire antennas for 1 kHz – 30MHz can be connected to the green “High Z” connector. 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).

2018-07-27 · It allows you to have 3 broadband antenna systems. 1 for Ham Lower Bands using High Z input, port 2 for say 50 to 1000 Mhz, and port 3 for 1 to 2 Ghz. However you may want to use them. So I am wanting to build some kind of Long Wire Antenna for the High Z Input. Thinking a Beverage Antenna of maybe a loop around the house. I have the loop mounted outside on the tripod and RCA antenna rotator 7 feet above ground. I was BLOWN AWAY by this antenna’s performance.

This will greatly reduce the noise level and improves the Signal and Noise Ratio. LW1650 Long Wire 1.6-50MHz HF Antenna for RTL-SDR USB Tuner Receiver [DISCONTINUED] Portable wire antenna is a simple suite, contains all the necessary components. It is a simple and effective rapid deployment of shortwave antenna with light weight, small size, easy to carry and set up easily.

Receiver and antenna: Sdr Play with a wire loop antenna around the 1950's Siera domestic valve receiver and 20 metre longwire antenna.

It has wide range applications, especially in amplifiers, detectors, mixers, modulators, air traffic control, etc. This is why it is always in demand. With time, the SDR antenna has advanced, and its uses are branching out more than ever before. This homemade longwire antenna works great it improved my reception on 80meters to 10meters " 20 OVER " on my sdrplay.

I'm just using 100ft of speaker wire that I split in two. 2019-10-22 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. 2015-07-15 Multi-wavelength long wire: A true long wire antenna is multiple wavelengths long.

The SDR only has coaxial connectors, no direct wire connectors.

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.

After some research I happened upon VE3SQB’s site and a neat discone design program for Windows. Telescopic antennas are way too short for shortwave frequencies! There is one fundamental rule for receiving antennas: It must be at least ¼-wave long at the lowest frequency you plan to use.
