All band dipole Mk2 The All Band HF Doublet is often referred to as a random length dipole as it is generally as long as the available space within reason, but here are a couple of limitations to the ultimate dipole length

160M 1/4 Wave Vertical 160m vertical antenna project. It is 100' of Rohn 25G and a 20' aluminum stinger. The base is made out of four 6' power line insulators sandwiched between two Rohn base plates. 7/8' stainless bolts hold the assembly together. 32 radials 50' long and 30 radials 100'
