If you can't see this video, please insert this URL into your browser search box: https://youtu.be/jMJxc7IXtiM.  Although this antenna project is not "simple" as I've used the term, it's still an interesting video of a major antenna installation--in this case the Topbeam Low Band RX Antenna model WF300.  The antenna was installed under questionable weather conditions at Sergio's (PP5JR) QTH in Florianopolis, Brazil .  The installation was done fairly quickly by a well-trained tower climber and his team.  The only practice I question is raising this antenna during "bad" weather.  You just can't take a chance with rain clouds around you.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free e-mail subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

If you're have trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/KmeZ25jabWQ. Thanks to Larry (WD0AKX)(Ham Radio Guy) for this intriguing video showing Roger (NX0P) using a compromise antenna with good results from his QTH near Glenville and Albert Lea, Minnesota .  The antenna is a MFJ -1620HT (for 20 meters), using a metal plate and three approximately 16.5 feet/5.03 meters radials.  He was using about 100 watts into this shortened antenna and made quite a few contacts.  Although short antennas are, at best, compromises, they can perform reasonably well with a decent ground or counterpoise system.  Roger's antenna arrangement would be suitable for those living in deed-restricted properties or for those favoring portable or emergency operations.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free e-mail subscri
