30 Foot / 9 meter Antenna Mast on the Cheap (074a)

In this video I will walk though how to build a 30 ft / 9 m antenna support for yourself using simple lumberyard lumber and hardware. I will also show you the modifications I made for my own version that I used at Moose Lake. Not everyone has a place to support one or both ends of a wire antenna. This problem is not foreign to the amateur radio operator. Back in the long past, they devised a way of creating their own 30 foot or 9 meter support using basic stuff from the lumberyard. It was 40 foot (12 meter) back then when they could get 22 foot lumber! I found this design in a 1940 American Radio Relay League (A.R.R.L.) "The Radio Amateur's Handbook." It is what I used as a starting place to create the antenna mast I used in Moose Lake, Manitoba, Canada when I lived there back in the 1990s. I made some modifications for my own application and it worked great. ======================================= Time Markers for Your Convenience ---------------------------- 00:05 Introductory Comments 01:24 The Design: Its Origins 03:10 The Original Design 04:05 Step#1: Lay out the lumber 04:14 Step#2: Bolt then together 05:03 Step#3: Splay out the legs 05:12 Step#4: Secure the legs in place at the bottom 05:51 Step#5: Add three more cross braces 06:16 Installation 06:22 The Guy Wires 07:22 Locations 07:27 Set#1: Midpoint 07:35 Set#2: Top 07:57 Lengths 09:00 The Pulley & Rope/Cord 09:59 Establish a level foundation 10:19 Base stakes for installation 10:33 Guy Wire Anchors 11:03 Putting the Mast up and into place 11:24 Final mast leveling 11:57 Modifications at Moose Lake, Manitoba, Canada 13:10 Final comments and tootle-oots
