Cheap SWL Antennas - Listening to Shortwave Radio With Scrap Wire

- Опубликовано: 1 апр 2023
- Shortwave listening is alive and well. From decoding digital tones, listening to broadcast stations or amateur transmissions - all can be a lot of fun. I have made a number of different dedicated receive antennas but these are the very simple versions I recommend that cost very littloe (even free with scrap wire) and can be built from scrap.

These ideas are only increasing the constant activity in my head that won’t let me throw away assorted bit and bobs lying about in my shop drawers that I will certainly put to use some day, assuming I will find them. Carry on.
The wire sold for fenceless dog things where you bury a wire around the perimeter of your property is very cheap. It works great and if it gets caught up you can just hack it off and make a new run.
I think it is great that people are still enjoying Shortwave Listening. I started around 1984, and still love it. Big changes, but still lots of great stuff to listen out for. It led to amateur radio for me and just last week I got my M0.
Ham radio?..after 23 years of calling me rear off. I'm moving on. They cut my cables. Have had officers calling at my door to look at my dusty logs and pocketing my qrp rigs. Thinking they were spy equipment. Slow to return. But starting again as odn-1 and all my receivers have each a personal "kit" with battery's and a lamp, a bit of cake and coffee, and chew gum. A log book I'm listing and watch on the net tks om later ps I park my car and toss out a bit of line about 10 meters does it. 73 from 72 old listener
'QRN' is 'natural' noise, such as the sound of lightning. 'QRM' is 'man-made' noise. A correction at
I grew up in a house with two-thirds of an acre of garden. Although I was interested in radio and electronics I knew nothing about aerials and made do with an end-fed length of wire in the loft. When I think now of the aerials I COULD have set up in those days, I could cry!
Conecting Co-Ax Cables: Put dielectric grease on th connection THENskide a heat shrink tube over the entire connection and heat shrink with a hot hair dryer.
When I was a kid I saw something somewhat unique. I think it was a "gain assist" for the AM radio band. Imagine a big hollow plastic disc about 12" in diameter and 2 1/2" thick that stood vertically on a base. At the center of the disk there was a big knob that you could turn with your hand. It was a completely passive device. I am guessing that it was a big LC resonator and the knob was for the variable capacitor. So you placed the disk next to your radio and set the resonance to the the same frequency that the radio was trying to tune in. I am guessing that this boosted the signal to the radio's internal ferrite antenna. Have you ever seen anything like this? I only saw it once in my life.
Sweet, very useful, now I just need to buy a house and not live as a renter anymore :)
The local scrap merchant can be a cheap source of wire
About 20 years ago, somebody wanted to take a SWL rig to Israel. We were in a Radio Shack. Customers, I and staff put together a package of a spool of wire, 75to 300 ohm coax to TV lead balum, 75 ohm TV coax, coax to radio adapter.
QRM: { interference) man made.
This is exactly what motivated me to schedule my general exam for this coming week and grab my first new (to me) HF radio. A long bit of speaker wire I had hanging around connected to an SDR dongle. I can hear so many HF QSOs that I want to get involved in the conversation too!
Killer ideas! I have been into radio for a while and that loop on the ground is great . Thanks a lot.
Rarely i get the pleasure to listen someone and get so intrigued within a min.subbed.
Another Quality Show Cal.
Great video and advise Callum. When I am on holiday in France I use an end fed copper wire attached to a tree and an atu. In England I upgraded to the mfj 1886 active loop as I am in a valley and works a treat. It's all about horses for courses as I have learnt over the years. Keep up the great content. I always love your live feed stuff.
I learned a lot from this video, and enjoyed it mightily! Your camera angles, drawings, and video examples really hammered the point home. I'll always remember the square loop and dipole antennae
Really enjoyed this! Well done. Don't know what else your channel offers but liked this so much I subscribed. Thank you from NE US.
Excellent video coupled with Great advise 👍👍
