Hi Alex, Cause is bloody rich! - His antennas are all matched and he probably has lighting arrestors that would stop anything. You can watch the episode on Ham Nation / Twit.tv ?where he makes the statement.. Ill see if I can find it and post the link
Thank you,
Brian Mackey KC1MAC? Hams don't let hams get stuck on 2 meter repeaters! :)

I wish I had my book about Ham on a budget done, but it is still in the works. You need to get an antenna up, even if not licensed. Get or build an antenna matcher. Plans can be found all over the Internet. If you decide on a resonant antenna, you can build a trap dipole, a fan dipole, or any number of other resonant antennas, such as a Marconi, which can also be built with taps.
Grounding is not necessary until you begin to transmit, and even then, if you have a good counterpoise, such as a resonant dipole, you may not need one. "BOB HEIL a king in ham has 24 radios and 46 other items that have grounds in his shack and NON are grounded"
I would really like to discover how Bob Heil gets away without a ground. Please share with us, as I myself have a shack on the second floor of my house, and RF can be a problem, especially on 17 meters for some reason... Now, about the three pronged plug. Your writing sounds like you are from England or somewhere in the UK, so I do not know what kind of connector your power uses, but you need a power supply for the 7K, and most power supplies use 3 pronged plugs (here in US), grounding the power supply with the house ground. If you are in the UK and bought a US rig, there might be some confusion. DO NOT connect the 7K to the mains (House power, or 120V here in US.) directly!!! It will kill it. You MUST have a 12 volt power supply capable of at least 20 amps, and 25 or 30 is better, since at 100 watts transmit, you will be needing around 200 to 225 or so watts input to the finals, plus other circuits in the radio for 100 watts out, so your current draw will exceed 20 amps, at least momentarily. This translates to a draw from your house power of just a little more than a 100 watt bulb. (Curious, isn't it - you can talk around the world with the equivalent of a 100 watt bulb!). Work on your license, and read the manual several times. Old radios (my last rig was a Drake TR-4, and before that a Swan 400), you just turned them on, let them warm up, tuned up and there you were. Modern radios (I have two) are a lot more complex... 73 de KC4BO

?Do as Simon says, and no, a ground connection is not needed as a receiver.? Just disconnect the antenna when not around to prevent stray lightning damage.? The ground ¡°may¡± become necessary when transmitting and you will know in that case.? When using a good resonant antenna a ground is not mandatory.? A ground becomes imparitive when using a tuner to operate on frequencies off the natural antenna resonant point.? All this will become clear as you learn the antenna basics.?
