For this 2023 i make a new study with this 2 antenna. Delta loop and delta end feed. This 2 type of shape for this antenna come with the triangle shape or Delta.
The different between this 2 antenna was the end point or the apex of the antenna.

The delta loop antenna i have been use from 2008. This is the best RX antenna. But for the 40m band use, i need to cutting out about 40 meters long wire for it. Then for the limited space at my home, here is the problem.
So i make a decision for the half wave antenna. Then the end fed half square came out. For me with 2 antenna at my roof top its not so practical.
I made a decision to create a combination with this 2 antenna. After a 4 month i tested this antenna on my portable operation, it work well.
Last 2 days ago i am run this delta end fed and the result so surprise. Only 20 watts with my Xiegu G90, its pile up on 15m meter band. for only 1 hour i can get 23 station.
The delta end fed antenna have a broadside at the top of it. On the horizontal side, its become the DX effectively antenna.
At the end point of this antenna, i am using the 49:1 unun. No counterpoise. This multiband antenna now work for me for 40m, 20, 15m and 10m band without any tuner.
This also very suitable for portable antenna. Now you can get 2 antenna on 1 shape. Deltaloop and Delta End Fed antenna
