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 wanted to see if a length of wire through the 9:1 balun would make a reception difference. I strung up about 25 feet of wire up about 10 feet outside. Best I can tell the current setup with the discone is still better. 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.

Even a modest length wire will give your receiver greatly improved reception with less static because the signal pickup is occurring some distance from the interference generating appliances in the house. “I have been getting into software defined radio via RTLSDR and found the stock antennas woeful for reception and picked up a tonne of noise from my LCD and laptop – though it’s hardly surprising. So to improve the situation and spend as little as possible I decided to make a discone antenna. 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. Thus, if your lowest regular listening is on 3315 kHz, your wire should be 70 feet long - minimum.

6 to 9 metre whip.

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.

Compared to a 25 foot long wire thrown over my neighbors tree, the 60 foot long wire was useless. The 25 footer worked well but I thought I could do better. I bought a Noelec 9:1 balun. I ran a the same long wire, in the same configuration, through the Noelec 9:1 balun into the RTL 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. The aerial wire is brought together with a 1.8 metre long earth wire and terminated into a short piece of coax and then an SMA male connector to suit an SDR dongle (not the BNC shown in the picture).

Software defined radio or SDR antenna is used for radio communications. It has wide range applications, especially in amplifiers, detectors, mixers, modulators, air traffic control, etc.

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.

Here’s a list of our favorites to make this easy on you. For the antenna, the goal is to get it outside as high and as long as you can. I've heard you should prioritize height over length of you have to choose, but haven't personally had to explore that trade-off. I wouldn't worry too much what material. I'm just using 100ft of speaker wire that I split in two. It is multistranded, insulated, and cheap.
