16 gauge would be fine any thinner and you might be pushing it.
Antenna attic ground plane gauge.
Here s part of my setup.
You will need a peak in your attic that is tall enough for the antenna to fit.
I have no idea how to ground it though.
Half dipole antennas ground plane monopole and marconi antennas are different they have parts that must be electrically grounded.
This antenna has all the reception power of an outdoor antenna but features a curved metal frame of reflectors that are designed for fitting easily into smaller attic spaces.
I used good 10 gauge speaker wire on mine.
I have read many mixed opinions on grounding in the attic so i have decided to ground just to be safe side.
Antenna mast grounding clamp ancable 2 pack electrical ground rod clamp 1 2 to 1 inch for antenna coax cable tv tower electronic fence etc 4 4 out of 5 stars 7 9 99 9.
My house ground rod is not to far from where the antenna will go but the copper will have to go out and down one side of my house.
Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space.
Other locals are using screwdriver style mobile hf antennas that can work with a proper ground plane installed as a base below them.
Four counterpoise wires of thick gauge these are copper wires that will create the ground plane for your antenna.
The only concern with attic mounted antennas is the space available to you for mounting.
I want to cut the cord and put a antenna in my attic.
I have several vhf ground plane and discone antennas in my attic.
The ge 33692 attic mount hd antenna is a notable example of an antenna specially designed for placement in the attic.
In my opinion the thicker the better.
Signal strength from distant vhf repeaters does not seem to be affected even when the roof is wet.
If the top of the antenna touches the walls or roof the performance may be affected slightly.
An obvious solution if you need concealment and have access to a space like an attic.
The wood structure is pretty transparent to rf energy.
Theses are sprout antennas like the one on a car and wire antennas for showrt wave and ham radio.
Aluminum plates or chicken wire can be used to create the required ground reflection.
