Small cheap linear loaded 80 meter dipole antenna

Image
If you lack the space to erect a full-length 80 meter dipole antenna, please try this linear loaded antenna project from Callum (M0MCX). Callum reviews the theory, construction practices, and testing to bring this modified dipole to life. If you can't see the video, please check insert this title URL into your browser search box:  https://www.youtube.com/watch?v=zWFU-VWOSJI Here are some remarks from Callum (M0MCX): he legs of this dipole are only 12.4m long (about 40 feet). See what you think. Callum. More videos: https://youtube.com/playlist?list=PLc... Antenna Modelling https://youtube.com/playlist?list=PLc... Tips and Tricks https://youtube.com/playlist?list=PLc...

How to build a coaxial trap for dipoles, verticals, and end fed halfwave antennas.

Image
Thanks to Mike (M0MSN) for this easily-made antenna accessory that allows you to shorten an antenna for 40 meter and 80 meter use. Coaxial traps can help you install an efficient antenna into a very small space. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=JjuL3470f4c Here are some comments from Mike (M0MSN): The Coaxial Trap, great for more than one band on a single antenna. The coax trap will also shorten the length of the wire antenna, making it perfect for the smaller garden. In this video I show and explain how to build a trap for the 40 metre band this can be used on an antenna for 80 metres giving you both 80 and 40 metre on the same antenna.. Needed for this build: 2 metres of RG58 40 mm former (an old mastic gun tube or waist pipe) Something to drill a hole the same dia as the coax wire strippers or knife soldering iron and solder. Enjoy I do hope you enjoy it and subscribe for more.. Many thank

DIY 9:1 Unun End Fed Random Wire Antenna for Ham Radio

Image
Exceptionally well-done video from "TheSmokinApe" on how to make a 9:1 Unun for an End Fed Random Wire Antenna.   Properly designed, built, and tested, this valuable Unun will allow you to have multiband HF capability from a random length end fed antenna. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=7AC99CNVuR4 Heare some comments from "TheSmokinApe":  This video discusses End Fed antennas and particularly End Fed Random Wire antennas for ham radio. Additionally, we go through the process of building a 9:1 Unun for an EFRW Antenna.

The giant Collins HF discone antenna at the Titan Missile Museum

Image
Thanks to Kevin Loughin (KB9RLW) for this fascinating tour of the massive Collins HF Discone Antenna at the Titan Missile Museum.  While not a simple HF antenna by any means, it remains a fascinating part of our Amateur Radio history. The video may encourage you to build your own discone antenna (perhaps for VHF and UHF operations.). If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=FbJN9QiOuHU Here are some comments from Kevin (KB9RLW): An amazing place and a unique and equally amazing antenna that you can hook up to!

Vertical Antennas for 160 Meters/CQ 160 Contest SSB

Image
  Building, erecting, and testing a full-sized dipole antenna for the 160 Meter Amateur Radio Band can be a challenging, difficult task.  It may be easier and cheaper to make a vertical antenna for the "Top Band." In this video, the contest team of "Steve and Steve" used two verticals to score well in a recent "CQ Magazine" 160 Meter SSB Contest. If you can't see the video, please insert this title URL into your browser search box:   https://www.youtube.com/watch?v=aX5TCP4SeSE Here are some comments from "Steve and Steve": Team Steve & Steve give an overview two vertical antennas that we use for the CQ 160 ssb Contest. We switched to a vertical design in order to pick up more DX stations. A dipole for 160M is nearly impossible to get high enough for DX. These two really worked well this year for us. Design and measurements below. Steve Ad4xt 1/4 wave elevated vertical: Base was 10' high vertical element 130' 14ga. copper stra
