Im using it as a "long wire", yes. I dont really have the space for creating a dipole (folded or not) tuned for 80m or lower. (20-30m and lower is what is most interesting for me). Its by the way about 65 feet (20 meters). About half is wound a couple of times between two beams on a balcony, so its ...

Mostly because I have 20m of coax lying around. I live in an apartment building, so I do not have any real possibilities for building a large antenna for LW/MW/SW. Streching a coax (or any kind of wire) out a window and about 7-10m to a balcony on the other hand should be doable. I also have the 1:9...

Hi,
I have about 20m / 65ft of RG58C/U which I am using as a longwire. No feed wire, just the coax directly connected to the P an N terminals of the RSP 2.

How do I correctly calculate the impedance to ensure that I use the correct UnUn of this?

Hi, I am a bit confused with connecting antennas to my RSP2 for HF/MW usage. I have tried to build a coax dipole using RG58, each element being around 10meters. It should be similar to this design, using about 13-18m of rg8 as a feed line. https://www.g4cqm.co.uk/G4CQM_COAXIAL_DIPOLE/G4CQM_COAXIAL_D...

Hi everyone, I live in an apartment complex without any good ways to ground my antennas. I've found that connecting the antenna ground to my radiator pipes really improves signal strength, the only problem is that it seems like those pipes carry a lot of current with them. I measured with a clamp-on...

Its the same for me on a stationary with an old asus mobo, on both USB2 and USB3 ports.
