Simple Ham Radio Antennas--Testing a bi-square antenna on 10 metres. Post #656.


If you're having difficulty viewing this video, please insert this address into your browser search box: https://youtu.be/xKNE25ZNgu4. Peter (VK3YE) has come up with another simple, yet effective gain antenna for portable operations.  In this video, Peter shows us how to build a bi-square antenna for the 10 meter amateur radio band.  The antenna is quite simple.  Take two ten meter/32.8-feet pieces of wire; form them into a square; support the top with a fiberglass mast; and tie off the sides to maintain a diamond shape.  Peter use a homebrew L-match to connect the bi-square to his HF transceiver.  You could also connect some 450 ohm ladder line to bottom of the bi-square and run this line into a 4:1 current balun.  A short length of 50 ohm coaxial cable will connect the balun to your antenna transmatch ("tuner").  This design can also be modified for use on the 20 and 15 meter bands.  This is an excellent 10 meter antenna, which will give you some gain without costing a lot of money.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are update daily.
