I need to start thinking about this and I would like to know what everyone is using as antenna for their receivers.

This is all I have.

Thank you!

Mine is just about the same, only a bit more adaptable. Made of 20 clip-leads strung across the lab. Sure I got loops, but with the cluttered bench... I do have a very short Earth ground, the frame of the bench, through the wall down to an 8' ground rod, about 6 ft total and it is bonded to the home ground.

About 650' of wire in a loop at about 50'. 450 ohm ladder line into the shack. Works great! :lol:

Shortwave-100 foot long wire antenna (back yard)
Scanner-MilTenna Omni (in the attic)
CB-Wilson Little Wil (on roof eves)

All work outstanding for my needs. Did not want to go with a tower or antenna farm, don't like the look on the house.

About 520' of #10 wire up about 50' in the tops of some old oak trees, fed with 450 Ohm ladder line.

Just to cross this off the list for interior, could you hook into existing wall cable lines for antenna?

You could try it, but use a .1uF capacitor in-between the cable and antenna to ensure no DC voltage is on the radio antenna input.

Thanks, Jim!

The only reason I even considered it because I do not have cable or Internet running through the coxal lines they're just wired throughout the house nothing plugged in.

But it looks like a long line is the way to go but I will have to see if there's a way to make this a quick and easy setup and takedown I don't think the neighbors would appreciate the lines all over the place.

In the hand sketches I think number two is the better setting but number one would be easily detached and setup but to get a proper length I would probably have to set this up in a V shape.

I am sure that direction plays into the setting. I will have to review what is best and check on city codes for set up.

For now I do like the clip leads setting.

Since I also transmit, the options are different I have two towers, each with a yagi, plus several band specific dipoles. And I shunt feed one tower for low frequency.

The little I listen to broadcast, I use a short wire for FM and ferrite coil for AM. Most of my bluetooth and wifi stuff has built in antennas. The same for my garage door opener.

I built a 23" diameter tunable loop, and in addition have a 240' random length long wire on my back acre.

BCB reception is about equal between them.

I wish I could have something better, but I am using about 50 foot of antenna wire insulated and turnbuckle tightened about 12" off the ground with nothing touching it. Then I have some 18 gauge speaker wire thru my basement window into the window well in my workshop in the basement.

Each radio is fitted with a length if wire and a spade connector that is plugged in when I want to use that radio. And be able to unplug it if it is storming.

My setup does favor around 10MHz because the total wire with lead-in is around 50 feet total. I get great reception on medium wave (AM radio) and bands 2 and 3 on my Hallicrafters sets work great. I want something better but this is as much as I can have for the time being and keep the peace.

receive only: 50 feet of 14 gauge going out the window and over the roof, two fishing weights hold the end over the peak so it remains in the air between the peaks

Transmit and receive: ~40m doublet in the attic + various 2m experiments

A lot depends on your location, What will work for you, might not be suitable elsewhere.

We live in south Manchester. We've always had good reception.

I've a dipole aerial in the roof space of our house. It was used in a previous location for 405 line TV.
I used it for my Leak tuner/amplifier for about thirty years. For the last twenty I've also used it to receive TV and have always got a perfect picture on any set, presently my new big screen Sony TV, (we've cable in another room).
I did change the cable from the old thin co-ax to the thicker stuff, ten years ago, but the picture was no better.

For AM and shortwave, I use a 108' long 14 gauge wire 16' off the ground. It connects to a 1:1 balun and comes into the house on coax. The antenna wire is 30 feet plus from my noisy (RF) house.

I've found how I couple my outside antenna to each radio is just as important, maybe more so, than the antenna itself. There are lots of variables depending on the band and the radio.

For radios with a ferrite rod or loop on the back, I get the best AM broadcast band reception connecting my outside antenna and earth ground to a 6" coil of 7 loops and placing it about 6" behind the radio's loop or ferrite rod.

For radios with a wire or connection for an outside antenna, I connect my outside antenna directly. But I usually have to experiment with the ground wire. Some radios have less or more noise with/without a ground wire.

I'm in a weak area as far as AM Broadcast. A long antenna wire in a suburban or metro area may overwhelm a radio.

I also have an antenna on the roof for my VHF/UHF ham setup. For what it's worth, that antenna works fantastic for some FM radios with connections for an external antenna. On the other hand, some FM radios don't like it at all and prefer my long wire antenna better.

Contrary to most folks here, I've tried many antennas and lower is better. Best is 1/16 inch off
the ground.

I use 36 feet of wire connected to a transistorized preamp, grounded to my SUV (which of
course has a big capacitance to ground). The car is 30 feet outside the apartment.
The preamp is 6k impedance in, 50 ohms out, no voltage gain, just emitter followers for
current gain. That means it is very low distortion. Below 4 MHz 100 feet of wire
gives a bigger signal but no bigger S/N.

The signal this provides (through coax) is not huge in voltage. Its fine for all boatanchors and about 50%
of domestic (broadcast) radios, even old TRF 1920s ones. For radios expecting high voltages from
long wires, I either use 100 feet of wire or a 4:1 step-up toroidal transformer.

Its amazing what it can do on good days, like yesterday, for LF and VLF (beacons), even with only 36 feet.
Velvety smooth low background with carriers 30 to 45 dB out of the noise. Even under bad conditions
WWVB is out in the clear.

Its supposed to have a 5 to 15 dB F/B or front/side ratio above 8 or 17 MHZ (depending on length) but I've
never been able to verify that. Its also supposed to be mostly vertically polarized.

i am using a rain gutter its about 70 feet total i have a wire connected too it that go/s though the window of my basement apartment it go/s into an amp supply ant tuner works great on 40 meters and other bands i am not allowed a wire ant so this is a hidden ant its the only way i can stay active as a ham Greg
