It is a 10meters piece of wire with a 9:1 toroidal transformer and a coax feed line of 25 meters Despite this long feed line I have no attenuation problem with RSP. Also I used 75ohm tv-sat coax and F connectors and -- again -- despite impedance mismatch with RSP there is signal to sell. This antenna is rigged on the roof (at 25 meters over sea
This was done for a few reasons including 1) We believe that the dipole kit is much more versatile and will enable beginners to get better reception straight away, 2) magnets of any type are no longer welcome on most airmail parcel The wire is 24 AWG single pair cross connect wire – connected together at the spool end. The wire spool is simply hung at the wall with about 20-30 feet coiled in the spool. The antenna was clipped to the RTL-SDR V3 antenna base without the telescoping whip – alligator clipped to the threaded mast. The base sat on the tile floor.
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 worst scenario is a long wire connected directly to the antenna input of your SDR, with no ground connected to the case of the SDR. A random long wire where one end is brought into your house is about the worst possible choice. About all you will receive with that is your own computer that the SDR is connected to.
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.
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.
and remember that more signal is better whether it's a wanted signal or if it's atmospheric noise. I use two antennas on my SDR radios. One I built for HF, and one I bought for everything else. A Loop on Ground antenna works good up to 20 meters and will shock you on Commercial AM, 160,80, and 40 meters. Just requires 60 feet or wire and 9:1 voltage Balun. A random wire is exactly that—a piece of wire that’s as long as you can possibly make it.
Whether the long wire antenna is a single wire running in one direction or is formed into a 'v'. rhombic or some other configuration. there are certain general principles that apply and some performance features that are common to all types. Strictly speaking a long wire antenna is just that - a very long piece of wire - many wavelengths long. However the term is widely used to describe a random length of wire used to receive and often transmit signals on the HF or short wave bands. In reality, the term long wire antenna, should be replaced with the term end fed wire, unless it the
You simply raise the tape until the length shows the wire length you need.

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.
Best I can tell the current setup with the discone is still better.
