A balanced antenna coupler and multiband tuned feeder dipole

If you want to make a simple 40 meter dipole antenna capable of covering several HF bands, you will need a balanced feed line and a balanced antenna "tuner".

In this well-organized video, Australian radio amateur Peter Parker (VK3YE) shows us how to make a simple balanced antenna "coupler" in conjunction with a balanced feed line to extend the frequency coverage of a basic 40 meter dipole antenna.

Here are some of Peter's suggestions for this project:

"Not your ordinary 7 MHz dipole. This works on all bands up to 28 MHz. It achieves this with a home made tuned feedline and balanced antenna coupler which is described in the video. The antenna is 20 metres from end to end while the feedline is about 8m long (neither critical). I only had room for 5 switches so omitted the 0.1 uH and 6.4 uH coils that VU2ESE used. Not having the latter may mean the coupler doesn't match all antennas on 3.5 MHz. I rarely operate there while portable so this doesn't matter. The source for the coupler circuit was VU2ESE's website at: http://hfsignals.blogspot.com.au/2015..."
