Just attach a cable to the ANT and it works, I just tried to test and worked

Insulated copper wire or Bare wire is used?

[@jacksprat7087]

Lots of unanswered questions here.

[@MuhammadDaudkhanTV100]

Very good work and cool looking

[@rickrose2235]

Can you explain why the receiver spring is spread out but the transmitter spring is not?
Since there is a phase to the (signal) helical windings they should match (won't you get a 3db loss if the phase of the helical coil is different)? Maybe that's just true for a helical antenna with a ground plane reflector?

[@anton7357]

I know nothing about antennas and stuff like this but for me different antennas on receiver and transmitter worked very bad. Only after I had installed 3 inch one on both modules it start working as it should

Can I cover this wire with isolation tape?

[@shnreum]

what type of copper being use?

[@ranjeetsinghjaggi]

After 28 turn of 19SWG COPPER wire signal is being match only 7 meter. What is wrong with me

[@ronginkagoj]

Nice

[@RahmatUllah-sy7ey]

Wow

[@kakslsd]

What is the maximum distance between the transmitter and the receiver ?

[@ElabIndustrial]

Please show my video final distance test

[@shivnarayan96]

Sir, What is the maximum distance between the transmitter and the receiver ?

[@ElabIndustrial]

Indoor 100 meter and outdoor open place 300-400 meter, thank you.

[@fernandovaldivia3953]

Hi, 24inch ?? can you please write the formula for the cable long for 433Mhz. Regards

[@ambreentabassum2464]

It is calculated by lemda/4...wavelength/4 , you can get wavelength as c=f(lemda)

Range koto etar??

[@manojsahas]

Hi brother, this is enamelled wire or normal copper wire??,, And am making 433mhz based project. But very close range only its working. I need minimum 40 meter surrounding signal range. Help me..

[@dindigulautomationwaterpro5145]

Yes I need to know also

[@dindigulautomationwaterpro5145]

I think we can use ordinary TV cable. th-cam.com/video/5jpQmbdypCw/w-d-xo.html

[@RoryMcDuff]

No need for a helix, a 16-17 cm long wire would make a much more effective antenna and definitely not much longer than those ones ..

[@bekiryufka]

No i've tried querter of wavelength is not that good. I mean it works but range is limited.
