Lets mount my Rangemaster at say 30 feet on a wood pole. My CB whip is installed. Then I crazily (is that a word?) connect 25 feet of wire to the ground terminal and bring it down the pole but I don't connect it to ground or anything for that matter. Since it is not connected is it a ground lead?

Druid Hills Invents Fire Starter
Druid Hills is brilliant to think of this... "Lets mount my Rangemaster at say 30 feet on a wood pole. My CB whip is installed. Then I crazily (is that a word?) connect 25 feet of wire to the ground terminal and bring it down the pole but I don't connect it to ground or anything for that matter.

If you post this at the other site we will have a raging inferno before noon today.

Disco Inferno, burn baby burn[/i]
With all this heat in NA, there are probably burning regulations in force in some sectors, so follow the fire regulations in your local area, or in addition to self imposed agents, you'll have forest bears in ranger hats looking in your windows at night and checking your wires.

The 25' wire is not a ground lead. The antenna is a 34' asymmetrical vertical dipole. That's assuming the audio and power cables aren't grounded anywhere.

Actually It Was Not a Ground Lead
Mister Druid Hill's opening question only asks whether his described wire was a ground lead.
The plain and literal answer is that it is not a ground lead.
DHR never asked, "If it's not a ground lead then what is it?"

Now we have a davec & a Davidc. Might I suggest a name change for the former to avoid confusion?

About the Dave and David C Situation
DavidC asked: "Might I suggest a name change for the former to avoid confusion?"
Carl acts naive and asks - Which one of you is the former?

Name Change Procedure
Changing your name might require the approval of the ALPB.

Just trying entertainment. I was surprised that the Resident Hobby Agent could not be baited. I thought your question was rhetorical but figured I'd put in my 2 cents anyway. I have a question for you about antenna top hats. Being that a symmetrical, horizontal top hat is essentially non-radiating, how might the FCC count this toward the 3 meter Part 15.219 antenna length? I've searched and read many FCC NOUOs without finding top hats mentioned. 1. Measured from the edge of the top hat to the mast and then down the mast to ground? 2. Measured from the top of the mast to ground? 3. Or? |

I think top hats are for adventurous people, since I've seen accounts of very few accounts of stations that use them. In the Part-15 landscape, top hats seem to be a more experimental thing, done by those who like to tweak their systems.
One problem might be that unless you use a small hat, it will add too much capacitance for commercial transmitters to tune out. My Part-15 buddy just found this out, adding a few feet radius of top hat and now his transmitter's tuner is maxed out at the top of its range, meaning he can't lower the inductance any farther to account for the increased capacitance of the hat. His system still puts out a better signal though.
According to my research, a hat is most effective on the shortest antennas, so it's a great idea for a P-15 antenna station I think. Check out top hat simulators in software, there are simple ones where you can put the numbers you have into them, and see what different size and type of hats will do.

Have a few questions...(1) Not sure exactly what a "top hat" is but if it's non radiating, what's it for? and (2) same question about the ground lead that's not connected to anything? But the wire could be considered as part of the antenna and over the 10ft limit.
