Ham Radio HF Vertical Antennas-adding DX gain

Image
A good, basic discussion on how to improve performance of HF vertical antennas. Peter Waters (G3OJV) of the Waters and Stanton video channel does an excellent job of explaining the theory and practice behind vertical antennas. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=gVAUmncsiO4 Here are some comments from the video: he quarter-wave vertical is one of the most popular ham radio antennas. But are we using it to its best advantage? Peter Waters G3OJV, describes ways that may add some DX Gain to your existing vertical. Apologies for the noise on the audio track caused by bad placement of the radio mic. XIEGU New Audio Filter GNR1 https://hamradiostore.co.uk/heil-pras...

My simple and cheap antenna mast and antenna installation

Image
If you live in an area with restricted antenna space, then this antenna project from the "Wiltshire Man" may be for you. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=r1MEE8KyMWA Here are some comments from the "Wiltshire Man": Living on the edge of town with a small garden can mean difficulty in putting out a good signal, also local man made noise (QRM) can mean weak signals are lost in the noise. My solution is to mount the antenna away from the house and also use a horizontal antenna. A Horizontal antenna has big advantages in an urban environment. It is much quieter on RX. If you can't hear the weak DX signals then how can you work them. A good RX is of utmost importance. Not wanting to invest a large some of money on a purpose built mast I repurposed a few piece of scaffold tubing and a couple of swivel clamps. The whole mast costs less than £100 and can be folded over. The stub m

DIY VHF Antenna Tuner made from junk

Image
Here's an interesting VHF "tuner" project from "crookedninja5." This tuner can be made for almost nothing, depending on how much material and old radio parts you can find in your "junk box." If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=95tup1t9PGc Here are some comments and suggestions from the author: I needed something to make my clothes hanger antenna a little more broad-banded in the 100-200 MHz range, so I made a simple antenna tuner from junk... this would work for scanners too.... The variable capacitor can be any 0-365 pf capacitor... for c1 and c2 a ceramic or trimmer capacitor can be used... c3 and the coil is all you really need... About 8 or more turns on the inductor coil with taps spaced out every other turn. The rotary switch is from a old indoor antenna... everything in this vid was from a junk box, except for the RadioShack enclosure. Once you get the

How to build a cheap inverted "L" antenna

Image
If you're short on space for a full-sized horizontal dipole or vertical antenna, please try this design from Clint of the "Oxford Shortwave Log" video channel. This design is based on work done by Leo Paget (GM0ONX). The inverted "L" antenna is easy to make and and costs very little if you can find materials locally. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=iHuoyvXVbdo Here are some comments from Clint: Hi there, now that I'm a radio ham, I've been looking for ways to set up an HF rig with a decent antenna in a relatively small garden. Here is a design for a very straightforward Inverted L antenna, constructed from cheap parts that can be quite easily assembled in a day. The tuneable whip antenna I purchased for HF doesn't really work in a built up area and requires a superb ground plane that I can't easily provide. Kudos and thanks to Len Paget GM0ONX for the exc

Best Ham Radio Antenna for Small Spaces

Image
If you're looking for a compact, simple HF antenna for restricted spaces, then this "shorty-forty" design from Dennis (AD6DM), "TheSmokinApe", is for you. The key to this antenna project is the use of a 49:1 balun with a proper length of wire.  Dennis takes us step-by-step through the design, construction, and testing phases of this 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=v6U8jBEtWs0 Here are some comments from Dennis (AD6DM): In this video, I show a Ham Radio Antenna that I built for small spaces. The antenna is referred to as a "Shorty Forty" which is a shortened End Fed Half Wave Antenna for 40 Meters (EFHW).
