Proximity feed (quarter wave Lambda) Widens the bandwidth impedance...a little I didn't like mine , if YOU want to tweak it , WORK over the feed tab size and distance to optimize the impedance bandwidth
-
A little more bandwidth with the Proximity FEED TAB (instead of direct contact)But yagi bandwith is real limited...an NEW whole band Bow tie LPDA would have better bandwidth...
-
Company published VSWR
-
I'm goin to replace the squares with bowtie triangles to check if it gets better... do you have the N type connector posted somewhere...?
-
Jomy ,could you post the aproxímate dimensions...I wanna try and make it wider bandwidth)
-
-
I'll see this weekend what can i do...(i don't like Yagis tho) Gain without LENGTH is not Achievable...or a 4 element ARRAY (short) feeding network should be hard to build...Did you EVER try a disk Yagi inside a TUBE...?
-
STL (i have cst 2019)
-
Don't let the AMOUNT of Signals Fools you ,You can see in the video what FR4 does to a small signal Wlan card little power output (it eats it up) Right HERE can't connect to AP...LOTS of AP doesn't mean Good Connection...Good RSSI NEITHER , PACKET LOSS RX Quality is more important BADLY DONE TEST
-
the ONLY advantage of Dielectrics...is SIZE reduction...and looks...ALL metal is the best option...
-
I sent all i have on those (rar) file
-
That would show up as Sensibility (RX) Power Output (TX)
-
@Harry36 might know details of these methods...
-
They keep the 50 ohms shield with the 3 posts surrounding the inner wire...? maybe there is impedance matching there or is it a BALUN...? also there's a CUT by the shield of coax...
-
LOL ! NO WAY (no my cup of tea) but that Russian feed POSTS YOU KNOW IT WELL...(LPDA or Vivaldi would be easier to do and tune)
-
Feeding posts...(3 Of them and shield)
-
Double Bow Tie , How is fed ? (the coax braid to reflector UNBALANCED)
-
the coax BRAIDS wires have to be FIXXED by soldering , creating a solder washer and then you can add screws and a washer to FIX IT to the main reflector (it shouldn't MOVE !)
-
900mhz
-
Great gain if true...
-
VSWR (kroks) Gain 1800
-
copper wire same diameter...i dunno if the dielectric is needed...
-
Still testing , Imepdance needs some work still...But looks good so far) Copper tape under 40 cm long and wide...PES foam or PU foam dielectric
-
If noise is fix you increase SIGNAL = GAIN ...(adding directivity will also lower Noise from out of the main lobe signals) a bigger reflector might be enough
-
5G not available or not registered...so it might be just on 4G...(which has a practical limit close to 100MBPS)
