VHF/UHF Dualband vertical


Posted on Aug 6, 2012

Use for this antenna tube of 10mm diameter. Or you can use a brass rod of about 7mm diameter. The top one is a strong copper (brass) wire of 5 to 7 mm diameter soldered directly to the coil and mounted to the PVC isolator to give a strong construction.



Because the top wire is only 21cm long so this will be strong enough in a 6 or 7 mm copper wire, The antenna has a unity gain in a 2 meter band and about 5dB in the UHF band..
