If your TX antenna system is 0.5% efficient, a 200w RF deck meets that 1W limit. "Practical" in this scenario is a standard 160m vertical with a trash-can sized variometer for loading, and lethal HV at the end of the wire that melts through. Guess the hidden word in 6 tries. A new puzzle is available each day. The meter indicates drain current. Ignore the two attenuator boxes on top – they aren’t needed. The power supply is a switch-mode type, 12 V 30 A and 5 V 30 A, from an old computer server. Operating 630 m requires quite different strategies from those used on higher bands. Because antenna efficiencies are generally very low, signals are. Dwayne Rogers KC5GGH of Louisiana posted his version of a 6-meter Squalo Antenna on Facebook. This is a pole-mounted squa re lo op antenna. Loop antennas are typically great performing antennas. They are usually very quiet when used as receive antennas. Dwayne reports that he was able to tune it to 1:1.1 on the 6-meter band.

The meter will quickly tell you if your antenna is too high in frequency (capacitive) or if it is too low (inductive) so that the proper corrective measures may be taken to resonate it within the 630m band. Once resonant, attention can then be paid to bringing the impedance match as close as possible to 50 ohms and a 1:1 match.

So, most hams will most likely be able to transmit a PEP of 100 watts or maybe more while remaining well below the EIRP limits of 1 watt and 5 watts on 2,200 meters are 630 meters respectively. 5) Maximum antenna height is 60 meters (about 196 feet) above ground. Most folks will not come close to putting an antenna up this high. Peter, The SAC PC-1000 autocoupler is the real prize in my 630 meter station. My transmitter is a SAC SS-250C with only 25 watts output and the EIRP is estimated somewhere between 20 dbm and 26 dbm, so a more powerful amplifier is in my future, along with some antenna improvements. Still, I've made 3500 km JT9 contacts when conditions are good.
