Sort of. PL259’s have a much greater impedance mis-match between the 50 ohm coax and the connector, whereas N-types were designed to have the lowest possible impedance mismatch. This means that there is significantly lower reflected RF at an N-type connector compared to a PL259.
At 2.4GHz I wouldn’t be suprised if the numbers were in the order of ~3dB loss from a PL259 over an N-type.
Even high grade UHF radios don’t use PL259.
yeah i guess so
Is he Dutch?
IS THIS antenna work!!!!!!!!!!!???????????
Man he talks fast :S
you can use a PL259 (plug & barrel…CB plugs)
But IS it work!!!!!!!!!!???????
there is a difference between “seeing” a wireless network and actually being able to connect to it. If the signal is too weak, you’ll keep getting dropped.
IS it work!!!!!!!!!!???????
Where can i get BNC connector
holy fuck! 7 with normal and 21 with ultra !
i buyed one antena like that and i got 62 acces points and with the normal just 23 accespoints COOL!
IS it work!!!!!!!!!!???????
Hey man…turns out that frequency of operation is decided by the circumference of the helix and also that gain is increased with increase in length (keeping everything else constant).
No, it its more complex than that. Best stick to the design here. You could make the helical part longer keeping the spacing and diameter of the helix the same.
Wrong! The spacing decides the frequency.
where did you get the BNC connectors
No…the length decides the frequency of the signals that will get picked up. And Wi-fi works only at certain freqs (around 2.4 GHz for eg:)
ride it then
you can add to the length (more loops) but keep the spacing the same
gotta love the Dutch
