Baluns on Log Periodic Antennas
This is the electrically ideal method of bringing the feed line back to the mast from the log feed. This method keeps the coaxial line away from the balanced transmission line formed by the boom. This works with ANY log periodic and good balun, including 200-300 ohm balanced systems

Coaxial balun
I used RG58 coaxial cable since I use less than 300 W power. Better is the use of the RG142 Coaxial cable with Teflon dielectric, which handle a power of 2 KW at 144 MHz with a lower loss also

End-Fed 160-10m Long Wire
diy 9:1 a un-un unbalanced to unbalanced transformer the heart of the un-un uses a type 43 ft240-43 core and consists of a trifilar 3 wire winding arrangement around the core
