I am looking for 1800 4g not 2600 and with 75 ohm. I read on LAN 23 but I had headache with the false traduction and A lot of negative critic

Yes I would like have this offset for 75 ohm it's possible mister jomy?

Long threated shaft. + Many screw hex ( diameter 10 mm)

It' works perfectly

Practical time

The improved helix antenna

Great Yes 16 DBI estimated ...

Yes 16 DBI estimated ...

Yes 107 degree is the best it took 1hours and half to finish it .thankfully I had already 2 disks 64.2 mm diameter. I got 57 % signal with double biquad and 83 % signal with this Julungaz antenna. It's worth to Make.

It's working wonderfully.

My hand made according to your friend julungaz

Sorry monsieur Jomy that's what I found on the site .

i think when the diameter 65.3 mm is better

great easy to make does it need balan ???

Thx jomy I ll try it

i agree CLANON But the 1/4 lambda guide is so different , WICH PROGRAM IS CORRECT

https://www.changpuak.ch/electronics/cantenna.php why i GOT big differentS resultS of 2 calculaters ( fr 1795 ,DIAMETER 110 MM) CHANGPUAK L = 0.75*LG = 122.16 / cantennator = 274.4 ( so long). CHANGPUAK LG/4 = 40.72 mm / cantennator = 91.5 mm ( distance bottom to probe)! any way for DIYER changpuak calculater is suitable becuz cantennator needs very long can (274 mm) but wich programm is right ???

Jomy in m willing to assemble 2 double biquad. Can you give me the distance between it and the length of cable attaattachment? The velocity facter is introduced in kamda/4 ????;;
