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.

Recently Chinese manufacturers have begun producing a low cost wide band (100 kHz - 30 MHz) magnetic loop HF antenna known as the MLA-30. The loop can be found on eBay for under US$45 with free shipping. In the past wide band HF loop antennas have not been cheap, normally costing $300+ dollars from manufacturers like Wellbrook.

In its simplest form it is exactly what the name say’s… A Long wire. Long wire antenna’s are only effective if you earth the antenna or the receiver in some way. This type of antenna is generally only suitable for the HF bands up to 30 MHz. High impedance wire antennas for 1 kHz – 30MHz can be connected to the green “High Z” connector.

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.
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.
