EFHW Antenna VS Dipole - Field Strength Measured.

Показать описание

Comparison between the EFHW and Dipole on 20 meters. Center support is a fiberglass mast. Test shows field strengths are identical.
Note: The swr on the EFHW was about 1.2:1, a bit higher than the dipole however it remained the same across the entire 20m band whereas the dipole was quiet narrow. This shows one more advantage of the EFHW. 73

I know you made this a long time ago, but I just ran across it so it's new to me. Nice work, and thanks for taking the time to do this! I'm not sure you could have made it a more even, fair, real-world comparison.

Thanks for your clear, straightforward videos, Steve. It's really helpful for those of us who are new to antenna construction and design.

Amazing that the end fed and the dipole are performing the same! Thanks for the video! ;)

Nice video Steve. It should not surprise anyone familiar with the theory of EFHW antennas, but it is valuable to see it confirmed practically.

EFHWs are my favorite QRP portable antennas and I never use a counterpoise with them. What little coax is used provides all the counterpoise needed. Fast and easy to setup and tear down, and they perform great. N6ALT

Excellent test Steve, often wanted to try this comparison. Great video.

Just what a needed to know. I worked out that they should be the same, but seeing it actually demonstrated and with such care is perfect. Thank you for your thorough test

Thanks Steve for taking the time to A/B an end-fed dipole! XYL k6sew and I are going full-time RV'ing and I'm counting on an end-fed dipole for hf operation along with my Buddipole Vertical. 73/k6sdw

I was just watching some other video these days and realized I should build a simple field strength meter to use for tests. Thank you for sharing this. I always thought a dipole is a bit better. In my location building a dipole is hard so EFHW is for me )). Now I stay relaxed as it doesn't seem to be any diferenfe. 73

Yes, several have complained about the "near field" signal but don't understand the whole point of this test.
Modeling software indicates that on the antenna's fundamental freq. the radiation patter is exactly the same no matter where it is fed therefore far field results don't reveal anything. All I was doing was demonstrating the efficiency of the transformer and feed system so wherever I go with another receiver won't matter. Besides, 10 wavelengths would put me in the neighbor's yard a block away. I've moved 40 miles away now so don't expect me to put this thing back up for another test just to prove the same thing over again.
My main antenna presently is a 80m horizontal loop at 100 ft high fed with home brew 600 ohm line. Works fine on all bands.

That Corsair II looks like a lovely radio!

Very good comparison indeed, End Fed Antennas work well in my very small garden, Far better than Dipoles ! Thanks mate 😀

Thanks so much for doing this, I just posted a question in the efhw group and them came here and see you information...

Thanks for making and sharing this video Steve. Cheers and 73! de W3LAM

Thanks for the video. Very nice QTH you have there.

Very well done technical comparison, congratulations!!l

Super work
But why antena is must?
Antena is a cable
But work is great.
Have a nice day for you.

I've never use a counterpoise on a end feed antenna and have QRP DXCC.
They are my main antenna both from the condo and in my ops from the national forest twice every month.

Nice. Very helpful. Have found my efhw to be valuable with all the bands that I can use. Performance seems the same, though sometimes I wonder if it doesn’t quite hear as well. Maybe it is just me😀

PercivalFakeman

Yep, well its the same antenna fed at two different points. Interesting point that the end-fed configuration is more usable on other bands..
