- Described is a simple inverted-V antenna which, when used with a balanced ATU, can be used on all the main Radio Amateur HF bands (80, 40, 20, 15 and 10m). The cental support is made in such a way that the wire can be coiled up for storage when the antenna is taken down.
- Connecting centre fed antennas, dipoles, yagis, rhombics, loops to coaxial cable, unless care is taken, it is not difficult to end up with feeder radiation resulting in power loss and the radiation characteristics changes
Antenna Gain to ERP
- A radio's transmitting power can be concentrated along the horizon by use of a GAIN antenna. Although you may still be transmitting with four watts of power, your effective radiated powerwill be greatly increased. This table shows the effects of antenna gain on a transmitter with 4 watts of transmit power.
- The signal forge 1000 signal generator is a portable, high-performance digital and rf signal source with a 1 ghz frequency range. features include digital, differential and ac coupled outputs
- SigJenny turns your PC into a flexible and powerful audio signal generator for free.
It can create multiple waveforms, sweep, fire single or repeating tone bursts. You can save your sound as a wav file, display a frequency response, use SigJenny a bit like an oscilloscope, and do a very good impression of a police car!
Amplifier for 15 and 17 meter band
- The two linear amplifiers are ment for use with QRP SSB/CW/FM/AM transmitters on the amateur bands 15 and 17 meters can be powered from a 12 volt DC supply by ON6MU
