Semplice dipolo rotativo per i 12m e 17m
Un dipolo per i 17mt rotativo con un Balun 1:1

Dipolo accorciato per 40 80m
La sintonizzazione dovrebbe iniziare sulla sezione 40m con una distanza di 10,5 m

The FD4 (FD3) windom antenna
The 4-band Fritzel model FD4 is a special version of a Windom antenna. It is a half-wave long on the lowest frequency

T2FD squashed rhombic
Denominata anche T2FD Terminated Two Wire Folded Dipole Antenna, si tratta essenzialmente di un dipolo ripiegato

The HF Antenna
The end fed wire antenna lends itself readily to QRP and portable operation.The Tuning capacitor in the AMU can be a 365 - 500pF

1/4 Slopers 40/15M Band

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

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 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 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
