I was watching this string of videos and remarking to myself that one of the things I like about them is you don't torture us with obnoxious music as many do. In fact I very much like the music and find myself smiling and tapping my foot. Then, in the credits, I saw that you wrote it, and no doubt played it. What a plus. I like you personally, I like your videos, and I like your music. Besides all that I'm learning something every day at age 77. Nice job Peter.
Thank you Peter! This is a very informative series. I'm blessed with plenty of space, but vexed by having very little structure for an L or inverted V config. I'm in a 2nd floor apartment and plan to hang one end from a tree with the feed point slightly above it at the house. The antenna -a Nelson EFHW 40-10- just arrived today and I hope to be OTA tomorrow. 73 de K1NKX
Would it work if I ran the vertical portion of the L attached to an exterior wall? Does it it need to be in free space? I just recently got licensed and live in an apartment. I'm trying to figure ways to make antennas work with the space I have.
I would try and avoid direct contact to the wall. Try and space it around 12 itches from the wall if possible. Maybe a bracket on the wall t bring the antenna away from direct wall contact. 73s Peter.
Hi Peter - with the L shaped antenna would it also work coming horizontally from the transformer unit then turning up vertically half way along the wire. Up a tree for instance.
@@watersstanton Hi Peter - Thanks for the reply. Yes it does work - I tried it this afternoon. Made contacts on 20 and 40 as far as Bulgaria. No ATU needed. 73 from Frank - Towcester.
question , I heard from other sites that if you take a end fed wire ,and run it in a 90 deg or more that it will decrease its effectiveness ??? your view ?
Well normally you bend an antenna because you have no alternative! I doubt there is any change in efficiency, but rather in the radiation pattern. Sometimes that can be a good thing. 73s Peter.
Hi Paul, there are conflicting opinions on this. My transformer is up in the air and I tried earthing to heating system and to a direct earth. I found no difference but of course the earth connection was a significant length. Using it portable without an earth works fine. Peter
@@watersstanton yeah there is conflicting opinions, I follow Steve Ellington and his testing with this antenna, he has a video with various grounding tests that show how much more current is on the radiating wire with a modest ground, if nothing else grounding would help with common mode current on coax

Many thanks Jim. Nice words. Glad I can help. Best regards. Peter.

Thanks, cause I am fighting against my end fed for about a half year looking for the right position in my small garden...;-))
Good to see this put into practical use.
Thanks. Peter
Can i ask, for a 40-10M end fed antenna, what's the minimum length of coax?
Hi thanks for a very informative article what radiating pattern would I get from the inverted L antenna as against the inverted V 73s from Trinidad.
Nice to hear from you. 73 Peter

Hi. It will certainly work. Try it. 73s Peter

Can the inverted 'V' shape run horizontal, parallel to the ground or at an angle, instead of vertically?
Yes it can. 73 Peter
So you are not going to open the box?
Is there any advantage to suspending an end fed antenna over a body of water, like a swimming pool?
It's the same as a dipole. The better the ground, the better the results.
Good presentation wondering why you've not mentioned grounding the transformer

Hi,is the transformer ratio 9-1 or 4901 ? 73 de m3vuv.
49:1. 73 Peter
