Antenna Telescopica FT817
La costruzione di questa antenna portatile e' semplicissima, un paio di ore di lavoro e risparmierete centinaia di euro

Antenna multibanda verticale portatile
Con bobina di carico alla base a prese commutabili tramite doppio commutatore elettronico e visualizzatore a diodi led

Antenna telescopica per FT-817 adattata con un toroide
Una telescopica, un toroide e un commutatore, ho pensato di farmela da solo

1/4 Slopers 40/15M Band The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 MHz and the top fed sloper was the most convenient installation having the least impact

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'

DHD Double Half Delta

DHD Double Half Delta This is a dhd double half delta in theory it should return a low signal but with a good s - n ratio roughly like a beverage

Visual CW Tuning Indicator

Visual CW Tuning Indicator Many transceivers set the CW transmit off-set equal to the set's sidetone frequency. But it was left to the operator how to match incoming signals to the sidetone for one-frequency QSOs an awkward and time-consuming procedure
