  1. Jomy do you can simulate only this double dipole with reflector...without directors ?
  2. Well Ok ,maybe i try to build .i have one spare piece of 12x12 cm zinc metal plate as reflector.
  3. Yomi it is video about double - dipole with reflector, i must say that i never see before such a antenna . Is is maybe better than classic biquad? IF IS ,then is worth to build..right?

    Here it is :

    . Exactly....and i don't what is mumbo.jumbo simulation talks means

    I must repeat my question : Do you have on your wifi card any program which show you signal strength? So it is very simple to test..in which case is better or larger signal ,with isolation from metal rod or without isolation. I can bet without that better reception is with isolation between active plate and metal rod. please let me know do you can do that test!

    Thank you jomy on simulation. vars-cat forget about simulation ,every simulation show optimal or ideal values and don't represent real things. Do you have on your wifi card any program which show you signal strength? If you have such a program you will see a difference in signall strenght when active plate is connected to rod and when is not . There is no speculation about that and i know that from my experience. This antenna as such is asimetric half wave dipole and as such require isolation between active element and radiator/reflector which must be grounded.

    Thank you jomy on simulation. vars-cat I am really dissapointed in your explanation, active plate 68mm dia MUST BE ISOLATED from metal rod, big last metal plate is REFLECTOR 90mm which there is no need to be isolated from metal rod, finished copper plate can be spayed with metal primer to protect copper.
  9. yagi

    heh yes, and most correct also would be to use plastic rod with plastic screws
  10. yagi

    Just look at the profile picture ,it is easy to build,and remember ..active plate must have be ISOLATED from ROD/ bar
  11. yagi

    In fact it is not hard to build this antenna at all. First you must have isolation tube beteween rod and active plate like this:
  12. Here is another loop antena for tv
  13. WELL yes Inc-royavle ..pff incredibile 16dB with reflector and reletive easy to build!
  14. It is DVB-T - digital video broadcasting - terrestrial ok so range is 350MHz,,,, so you mean is he can cover whole range He can if the size is for 470MHz...
  15. bandwith of 350Mhz ? what is that ? i am not sure...here where i am there is no any TV station that emit on 350Mhz in DBV-T all of them are above 470MHz so if you can pick up lower then you must recalc biquad dimensions which must be more larger
