you should post a video on how well it works, i wanna see the results..

[wonderer4711]

I posted that video about 4 years ago! From that time on that antenna worked well for about 2,5 years at the roof of a friends home to my "appartment" for Internet connection sharing. After that we use it for Data transfer between our two homes. works well till now!

[Helloeveryone02]

how do you made it? tell me please

[wonderer4711]

Taht is a "normal" Helix antenna. It would remain in every "How to build an antenna" book for radio-amateurs and was only calculated for the "new" wavelength.

Nice coils, but does it need to be so long.?

[wonderer4711]

Yes.

[Isosphere]

The aluminium rod in the center kills the gain. Use a plastic boom instead or use a

plastic tube for the coil.

The aluminium acts like a short circuited ballast in the center of the coil. The magnetic field exists inside the wire loops, the electrical field remains outside.

Try to measure the gain.

You will be surprised how bad it is compared to the theoretical value for the number of turns you have got.

Directivity and impedance my be ok, but the gain is what matters.

@SouthTuningSwiss

i am from pakistan i am interested to check your connection

what will i required for this

@SouthTuningSwiss 100Km! Wow, I've been sitting here anxiously awaiting a chinese-made yagi.. supposedly 25 db gain. I'm really hoping it at least outperforms my cantenna. I'm hoping just to get down to the next block while you're talking about across the ocean, lol! Good luck with that. Oh..500W, won't that give people breasticle cancer or something?

are you a radio ham

@SouthTuningSwiss I'm interested in you building me a circular 2.4 ghz antenna.with 24dbi. How much will you sell it for?

[SouthTuningSwiss]

My rig with 130cm sat dish and a personal design(secret) feed antenna device is providing gains around 39 db!!!! My longest connection is from Lugano(my homecity) to Milano, italy, about 100Km away from me, using my sat dish antenna and a 10W amplifier with 27 db gain in RX!!! And this is only the begin...im searching a guy living in the states for try the first transoceanic WLAN connection!!! I have plans for build 500W Microwave linear amps...someone interested?? Write me please!! Bye bye!

[SouthTuningSwiss]

For WLAN frequencies a helix antenna is like a wheelchair for a healthy runner!!! Begin to play with parabolic dishes and feeding antenna design and you will believe real gain and distances over 10 km....its not a joke!!! Helix antenna is good for 70cm band but not over! Best regards from HB9ZLX

@Carmador Cool comment, bro.

señores tengo un programa ke resive y envia internet por la misma targeta wifi si lo kieren me dicen =) ConectMyWiFi

esta el video en mi canal

[witecracker2]

how much does it cost? and where do you get the parts???

great!!! stuff!!! mind !!!
