Idea Of  Jomy. I made it. The last year 

The. Easiest way to fix it. Is. To. Bend the cable

The. Easiest way to fix it. Is. To. Bend the cable

the direct connection  of the  cable to the  feed point distorts  the radiation pattern   

i love your work  my  friend   its  writen  in blue   the feed point  34 mm  from the  center  the antenna  is  made for 75 ohm

Greetings  JOMY   very excellent job. i m so curious to know the level of isolation of 2 ports (crossports)  in your antenna design.  being so busy i will post the dimensions as you asked 

I made this 

 VERY EXCELLENT its possible with MIMO feeding !!!!

Or like this

yes  exactly  

Greeting  mister Jomy    need help  to  make  AXIAL (FRONTAL) FEED for parabolic dish (  no offset feed)  for 1800 LTE MIMO 75OHM   and thanks by advance 

DIY Frontal Feed  MiMO system.For  mobile communication   B3 (1800)  4G LTE  with good isolation of 2 ports preferably  75 Ohm

Use ordinary metal shears for cutting. use a drawing compass for marking.

what was recommended to you by the message above applies to cutting ceramic tiles or plastic. when cutting metal with such a tool of metal sheets, very serious injuries can occur. do not use such cutters!

VERY DANGEROUS WAY,   BE CAREFUL ...!!!

very bad response!!!!

Jomy Is it possible for 1.8. Ghz    75 ohm ??!!!

How about mimo system. The. Decoupling. Of. 2 ports 120 degree.  Is it. Good. ?  I want   to  see the s1s2. !!? Thanks by advance jomy 

thank you mister jomy   u are absolutely right  i tried  without dielectic factor  and does not work.!!

Another repeater conception 

thanks jomy   health for you  i will use  nylon bolt for support

I want to try  one for 75 ohm  as repeater 

Interesting   want to try. It.    Jomy plz Wich modification are done ? 

,,,it needs laser cut ...!!!
