Title: HF Antennas what does everbody use for listenning
Post by: AUSSIE on May 05, 2012, 03:52:05 PM
Hi everyone thought i will start a topic what hf antennas we use for listening main intrest is hf aero bands also have a radio room at dads place..
My Antennas:
Wellbrook-ALA1530 Active
Wellbrook-ALA1530AL-1 Active Loop
Wellbrook-ALA1530L
Wellbrook-ALA330S

Dads Place:
Dressler-ARA40
Rf Systems DX-One MKII Omni Directional (2)
Rf Systems Dx-10 Omni Directional Vertical (2)
Rf Systems MLBA-MK3
Rf Systems MLBA-MK4

Here in Hawaii on the windward side of Oahu, I use a 20 meter dipole, a end fed long wire, and a Kinemetrics 1-22 mhz vertical. I'm a utility band listener and a ham both - mostly utility band listener though...

This works great here for utility band listening...

That's quite a lineup of antennas Lino!

I rely on three different antennas for different frequency ranges:

1.  BCB to 40 meters I typically use a 190' center-fed with an open wire feedline
2.  500 meters to 40 meters a pair of 85 foot triangular wire loops fed with RG-6 (K9AY in shape but bi-directional with one for N-S and the other for E-W)
3.  From the 20 meter band through 30 MHz I use a Traffie Hex Beam.

I'm very intrigued by the Pixel RF-Pro1B broadband loop and will probably install one after I finish another project I'm in the middle of.

I agree with Rob. That sure is some collection of antennas you have Lino!
From your list I also use the RF Systems DX-1 Pro MK II Omni-directional.

Hi Rob & Fred thanks also share a radio room at dads with 45 receivers we are in the process of getting down the antennas to check coax cables been raining very heavy we do that once  a year in the next few weeks...

Regards Lino...

Lino,
you can't beat a magnetic loop antenna for greatly reduced noise and by rotating it, you can null out another station.

Actually many antennas beat magnetic loops, but those antennas are much larger. A magnetic loop's noise reduction only works on near-field noise sources such as motors, transformers or street lighting, not ambient QRN.  Rotating the loop will help if the near field noise comes from a precise source... a single power pole transformer, for example.

Hi Fred main intrest for me is monitoring hf aircraft it took me a while to get the loops phasing the right position and height due and distance from electrical sources,I
am not an expert when it comes to specs dont even bother but i do have over 60 recivers and lots of antennas to know what works,All i can say about the wellbrook loops the performance is excellent..
