Combine from two parallel 300 ohm twin lead 300 300 \ / 150 | ? 75 Zi=impedance input of line Zl=impedance load of line Zo=characteristic impedance of line require Zo=√(Zi)(Zl) Zo=√(75)(150) Zo=106.07 ohm ?=106.07 ohm Z load = 150 ohm Z line = 106.07 ohm Z=(106.07^2)÷150 Z=75.00
Hi jop would like to know do you have the .stl file for the plastic parts?? Thank you8bay for new band UHF (470-608 MHz)
Parts Plastic for support of aluminum square tube (3/4 x 3/4 x 1/16 wall)
Antenna Dimensions in Inches
Parts Plastic Dimensions in millimeter
Is not necessary printed all the parts each one has his form to build.
Add analyze in 4nec2 antenna 4Bay (auto segmentation off) and an example of 8bay with harness all the archives this here:
