Arduino Shields Manual 2010 - 8 - Arduino LCD&KeyPad Shield (SKU: DFR0009) Introduction The LCD Keypad shield is developed for Arduino compatible boards, to provide a user-friendly interface that allows users to go through the menu, make selections etc. Way back when I was studying for my first ham ticket, an old Elmer wisely quipped, “all an antenna tuner does is lie to your radio!” He was absolutely right. I have since fine tune the 20 / 40 meter trap dipole and this is a really nice antenna for limited space. Some tuners are better than others in tuning in channels that are either too weak, too strong, too noisy, frequency range etc. I have play a little bit with sketches, read lots etc My project is a remote antenna tuner. The Antenna Disconnect Actuator is installed at the output from your transceiver, power amplifier, or antenna tuner in line with the antenna’s feedline.

K3NG is well known in Amateur Radio circles for his projects, using the Arduino platform to develop a number of very useful Amateur radio projects. Apart from that the kit also contains an 8GB SD card. Conclusion #3 : If your SWR (without the antenna tuner in the circuit) is not 1. HF Automatic tuner with an Arduino. Arduino Home Automation Arduino Books Radio Shop Hf Radio Diy Electronics Electronics Projects Ham Radio Antenna Electronic Engineering Tv On The Radio ArduiTuner This project describes an ARDUINO based automatic antenna tuner, for an end fed half wave (EFHW) antenna, dual band for 20 &. It is fed against a network of radials and has worked well over the years covering from 600m to 6m, with an appropriate tuner. They specify a vague "it can tune 1000 ohms". The Hi-Q antenna designer/developer has MINIMIZED these losses to an acceptable level -- the RE (Radiation Efficiency) is substantially better than ANY Submarine telescopable HF antenna to date. Those of Bourns cost around 23,21 euro VAT excl. The SARK-110 series of antenna analyzers are pocket size, multipurpose precision instruments capable of analyzing antennas or networks, generating or detecting signals and performing Time-Domain-Reflectometry (TDR) measurements on transmission lines. Its built-in SWR/Wattmeter measures SWR in 2 power ranges -- 300 or 30 Watts.
