Hy End Fed antennas are half-wave antennas that basically work similar to a Zepp or Fuchs antenna. Minimum handling and a relatively high efficiency.
The problem with a lot of portable antennas and antennas in confined spaces is the low efficiency of those antennas. Greatly shortened verticals need a lot of radials for higher efficiency, a dipole would need two anchor points and a heavy feed cable in the centre. Usually this is not possible when going on holiday or with only little space to spare.
In this case a well known antenna concept like the half-wave antenna helps out. Half-wave antennas can be end-fed, because of that the heavy feed cable in the centre is not necessary and the antennas are easier to install. This way only a light fishing rod on the balcony or a suitable tree next to the house is needed. The greater length (λ/2 instead λ/4) increases the efficiency considerably. Single antennas for lower bands use an extension coil.
Another trick by HyEndFed antennas is the transformer (UnUn) with a relatively high transfer ratio of 1:50. Because of that the high impedance of an end-fed half-wave emitter is transformed down to a level with which built-in tuners work well. Sometimes no tuner is needed at all and a counter balance is not necessary either. This is another reason for the antenna design, especially on holiday or with little space. Also, the transformer can cover higher voltage rather easily making HyEndFed antennas capable of higher power.
All power ratings in Watt PEP. All larger antennas have a PL-connector, the QRP and portable version have BNC. There are isolators at balun and at the end of the wire for installation. It may be possible that a guy rope is needed in addition.

Yaesu sounds like overloading from a 5 km signal.
You could use attenuator?
Hello Alex, that looks like a great antenna. Have you tried using it horizontally? I'm asking because I'm thinking about putting it up on my apartment roof between 2 PVC poles that are 2 meter high. Or do you think I will get bad SWR? Thanks! Dankjewel! Danke!
Horizontally for sure is great but you need to put the hot end way up in the air! 2m won't work in a usual neighborhood. Could work at the sea in the dunes but the best results you will get is when it's higher than 10m. But just try it out. That's the best way to find out. ;-) 73
@@reviewmirror Thank you Alex! I guess I can give it a try. 73.
@@dutchdrone1249 Yes for sure! That's what our makes that interesting. :-) Please let me know your results. Take care!
Hi !I cannot find this model on their website. Can you please send me a link to buy it on their website? On wimo is sold out. Danke!

Thanks for this, interesting and useful. Don't worry about your English, it's better than my German will ever be!
Thank you 😊 You're welcome.
No apologies necessary. Your English is WAAAAAYYYYYYY better than my German.
Thank you 😊
Servus, hab mir gerade die 23m Version 80-10m bestellt. Allerdings wohne ich in einer Siedlung und der draht geht bei mir vom Balkon (5m über Grund) zum Nachbarhaus ( über Grund15m). Bin schon sehr gespannt. vy 73 de OE5VIP Manuel
Also bei mir hat das nicht so gut geklappt. Störungen bis S9. Aber probier mal aus.
@@reviewmirror servus. Ich habs schon mit einem 20 Meter Draht probiert. S0 :-D Kollege konnte es gar nicht glauben
@@OE5VIPManuel Dann bin ich mal gespannt :-)
Really enjoyed the video. Hope to see many more from you . Thanks Fred.
Thank you. :-)
Why not to hang this end fed as a vertical?
Sure, possible.
Hi,
How do you fix the Spiderbeam into the earth? Without any post?

I am using the ground sleeve of a rotary clothes dryer. You can see it in the video.
Thank you very much, 73
@@jckim8604 You're very welcome Sir. Best 73's!
Is it placed I cement in the ground or just dug into the dirt? Also what kind of coax did you use? I found my spider beam bends much more than yours even using RG8x
@@davidw3260 In the dirt as it is a vacation location. I've used highflexx coax.
