| Using FT8 to check the Antenna |
On our last portable activity we used a HyEndFed antenna with impressive results. So I decided to buy one that fits into the garden. It is the 40-20-10m band version for 200w PEP.
The antenna is now mounted 5m above ground. Of cause that's way too low but it's the only way to install it here. The installation is easy. The SWR was ok out of the box. I shortened the wire a little and thats it. You see the results down below. SWR is good enough for now. I know it could be tune better if one takes a little more time for that. I had to shorten the wire before the coil a little and keep it a little longer after the coil to get the SWR right on 40m.
In any event, the antenna works really good for only 12m lenght. I love it.
How do these endfed antennas work? Have a look at the following links - They explain it really well.

And this is where I bought mine from. I sure would buy it again since it's nicely built and looks rock solid. https://www.hyendcompany.nl/

 |
| 12m SWR - The antenna is not made for 12m but works with the internal tuner |
 |
| 15m - not working |
 |
| 17m - not working |
 |
| 20m - working well enough |
 |
| 30m - not working :( |
 |
| 40m - working - I cut a little too short |
 |
| 80m - not working |
 |
| 160m - tunenable but not efficient |
