Hi
I try to build collinear antenna at 930 MHz ....
I build like this: https://cheatthezone.tripod.com/wireless/colinear.html
but instead 60mm _O_ 90mm _O_ 83mm _ measuring parts (at wifi f 2400MHz) I made racalculation at 930MHz and build with wires:
SMA connector =161mm _O_ 242mm _O_ 218mm
I have pure result! What is wrong?
Have anybody good point to make collinear antenna with simple wire and good gain?! (cca 6-9dBi)
