144/440 MHZ copper J-POLE antenna
This antenna is built almost entirely of hardware store items with the exception of thr feedpoint connector and works as well or better than most commercial
450 Ohm Ladder Line J-Pole For 144 & 440 MHz
The best part about it is that it can be used on 2m and 70cm and it is cheep and easy to build
A VHF UHF Dual-Band J.pole
The J-Pole has no ground radials and it is easy to construct using inexpensive materials. For its simplicity and small size, it offers excellent performance
