Antenna Drawing 23 cm
Si puo' realizzare in due orette, chi ha un po' esperienza

23cm Band Repeater Coaxial Collinear
The following pictures show the stages of cable preparation.Elements were cut 2% less than the published length to force downwards beam tilting

23cm 1296 MHz Bi-Quad Antenna
the bi-quad is also known as a double-quad antenna quad the bi-quad gain is around 9 db

Antenna Morgain for 40-80m This antenna has in its main characteristic, the fact that with only 20 mt. the 80 meters of space occupied it

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 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 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

Convert ADIF to Cabrillo Format

Convert ADIF to Cabrillo Format Have an ADIF file from amateur radio contesting, but the contest you want to enter wants a Cabrillo-formatted file? This is the tool that you need

trap-dipole-7-10-14-18-50-mhz

Trap Dipole 7, 10, 14, 18, 50 MHz Trap dipole 7-10-14-18-50mhz with balun coax cable

Diy Arduino CW keyer

Diy Arduino CW keyer I added code to read push-buttons on digital pins to trigger hard-coded messages like CQ and CQ SOTA
