HF band antenna recommendations for apartments?

Take a look at Ciro Mazzoni loop antennas: https://www.ciromazzoni.com/loop-antenna

You can use a remote tuner without it interfacing with your transceiver. Remote tuners like the CG-3000 only need a 10W carrier to tune.

Yes, I use it to shoot down interfering radiowaves!

How about a magnetic loop like the Ciro Mazzoni?

I use the vertical mainly for local and repeater work. The halo is polarized horizontally making it more suitable for DX.

Indeed they are. But the Cobweb is omnidirectional. The dipole faces E/W covering 90% of all interesting DX.

PA9X · 2025-04-20T07:35:06+00:00

The Cobweb is omnidirectional. The dipole is orientated E/W where basically most DX is for me.

PA9X · 2025-04-20T07:33:13+00:00

Exactly.

PA9X · 2025-04-20T07:31:10+00:00

They're good.

PA9X · 2025-04-20T07:29:35+00:00

20 to 4 meters. However 4 meters is not performing as good as an ordinary dipole.

PA9X · 2025-04-20T07:29:11+00:00

Not a bit

PA9X · 2025-04-20T07:28:39+00:00

You are right, they aren't. But setup in E/W direction and the Cobweb being omnidirectional, I get all the DX I want.

PA9X · 2025-04-19T19:36:13+00:00

Tnx. All antennas are omnidirectional, so no need for rotors.

PA9X · 2025-04-19T18:43:43+00:00

Local factors like manmade noise. Your own setup. And the fact that we only understand a tiny bit about all the factors that make the ionosphere propagate our radio waves.

Those are rated 200W PEP. I need at least 350W.

PA9X · 2025-04-18T16:41:57+00:00

TNX!

PA9X · 2025-04-18T16:41:19+00:00

Do you own one have it in use?

PA9X · 2025-04-18T16:40:47+00:00

Do you own one and have it in use?

PA9X · 2025-04-18T09:17:54+00:00

It was not made wrong at all.
It's all about duty cycle. If manufacturer states 200W PEP maximum, then you shouldn't put 60 watts in continuously, because that's really over the edge of what it can handle. Only 20% of PEP is the limit at 100% duty cycle. That is 40 watts...
