Moving the feedpoint changes the impedance because you're touching the radiating element at different places along its standing wave. Whoah! That never clicked before, thank you.
I am glad you enjoyed. 73, Paul.
Very well explained out to the Newcomers. 💯👍
Thank you so much, I’m glad that you found it useful. 73s, Paul.
I use wireless mictrophones (~500-600MHz). The first 5 minutes were great for me. The first time I have understand how impedence on a half wave antenna works. Thanks!
That is great, I am so glad that it was helpful to you.
Just realising the much easier setup with end feds for Pota , great video 😉
I agree! I just went to the beach recently and tried the EFHW, it worked really well with 10W. I made contacts as far Hungary. 73, Paul
It’s an awesome content . Love it .
Have my ham radio license in 1987 . But then came to USA to university and didn’t follow up with ham radio license anymore .
Only GMRS and CB for car convoy traveling.
I’m thinking about going back to ham radio 😊
Thank you for the kind words and I really hope that you get back to ham radio. I can really be a lot of fun. Hope to catch you on the air. 73, Paul
Nice video! Thanks!
Thank you. Glad you liked it! 73. Paul.
Hi Paul, nice video. I am newly licenced in the UK and just getting into end feed antennas. I found you video both interesting and very helpful with understanding the theory of antenna building. 73's MW7GQB
Welcome to the hobby! I’m glad that the video was helpful to you. Let’s keep an eye open for each other on the bands, it would be fun to chat in person. 73, Paul.
Great video would have talked about antenna height and location of antenna. Many hams live in the city and it's hard to get all the bands with a good enough vswr due to your surroundings. Ty
Thank you of the good comment, that might be a good topic for a future video. 73, Paul

No one has ever accused me of being a stickler for capitalization. Perhaps it's a secret rebellion against the tyranny of the upper case, haha. 73.
@@W2PAK No tyranny just (technical) literacy. No excuse if you haven't study electronics, you learn that in primary school, and everybody who works with electronics should write correctly (is my humble opinion), especially if you have the ambition of learning the others here on YT or elsewhere. 73! en.wikipedia.org/wiki/Unit_prefix
