Attic longwire antenna and SWL SDR setup

This video illustrates my attic longwire antenna with counterpoise. It has connections both to the garage (gator clip for a receiver's telescopic whip) and the living room (coax). The reception, shown here with gqrx and my RTL-SDR v3, is OK, but it probably would be improved with a longer counterpoise, ground connection, or outdoor wire.

Greetings from Sweden! You, Sir, just got yourself a new subscriber and a thumps up 🎉 I'm about to set-up this monster 😅 I'm a total noob so i need some advice❤ Questions. Why did you connect it to the wip antenna outside, was that the ground? If the wip is ground, you connect both attic wires to only one connector on the 1:9. Im a bit confused. Making a dipole by using both connectors. Making a longwire using one connector and ground it. I have looked for descriptions, but i get different answers so im about to go outside with a manometer and some wires and test the ohms. If i not reply to your eventual answer, well, you can send me a prayer 😂

Thanks for showing us around. I'm looking to do the same attic setup with an additional discone for vhf uhf and trunked DMR

You're welcome! That's a great touch! I had an FM broadcast dual loop antenna I was going to use up there for other frequencies but it's fixed length and I pick up FM fine so I decided against it.

Nice ! You are really digging into this .

[@walnuthills11]

Thanks, Scott! This was a nice setup.

I should show the balun and ground for the fence antenna. With that I got really really fantastic reception.

I appreciate your advice, I a beginner in shortwave listening. The white coax go to radio antenna. My radio is a Tecsun pl 330 I use a clip connecting to longwire antenna 50’ I really confused how connect white coax to a clip telescope antenna of my Tecsun pl-330 radio.Thanks 😊from Puerto Rico.

I gotta try this.

[@walnuthills11]

Please do!

Isn’t that a balun, as in for a balanced antenna such as a dipole and not for an end fed wire? I believe there is a mod, something about cutting a trace, that converts it for end fed. Thanks.

[@walnuthills11]

It is a balun, but I think one end is for a grounding line.

Cool. 📻🙂

Thanks, Jeff!

The only thing missing is a flux capacitor.

Your attic is kinda creepy! I’m looking to build something similar soon. Pretty sure my attic is equally creepy.

[@walnuthills11]

Nice! Lol it sure is. Your assessment is correct hahaha.

[@walnuthills11]

It used to have a resident raccoon...

Later Gater.....clip

[@walnuthills11]

Haha, indeed.

The white coax looks like a TV 75 ohm coax...

[@walnuthills11]

I think it is.
