I would like to hear from anyone here who owns and uses an active listening antenna?
How good are they, what brand and where did you buy would be of interest.

Re: Receiving Active Antenna
I built one of these kits http://www.ramseyelectronics.com/downlo ... ls/AA7.pdf
It works well as a general purpose pre-amplifier. I don't use it as an active antenna though.
In it's intended use, it performs quite well on VHF and UHF - forget HF indoors though. With computers, plasma/lcd tv's, and other gadgets running in the house, the noise level on HF is overwhelming.

Re: Receiving Active Antenna
Hi i have used a lot of different active antennas from Mfj/Rf Sytems/Winradio these are current ones below.
LF ENGINEERING-H800 SKYMATCH ACTIVE 10KHZ-50MHZ:
This antenna does a good job monitoring hf signals small in size 26 inch long 1 inch diameter must be away from electrical interference otherwise u will get a lot of noise on hf i got it mounted on the roof but will e moving it to a better location bought the antenna from Grove in america.
PALSTAR-AA30 ACTIVE PORTABLE 300KHZ-30MHZ:
This antenna runs on a 9 volt battery does a decent job with its own aerial u can also run a long wire antenna comes in handy when u are hf portable bought it from Tts Systems Victoria.
WELLBROOK-ALA1530 ACTIVE LOOP 40KHZ-30MHZ:
This active loop does an excellent job across all hf bands must be at least 5 metres from house so it can null out electrical interference i got it mounted on the alfresco room around 4 metres high and around the same distance from the comms room had it mounted 12 metres high but was to close to other antennas & around 1200 metres of electrical wire and wasnt performing good at all will be picking up a rotator shortly end it should improve reception planning to mounted higher where its located ordered from The Shortwave Shop UK & they will put the order for u to wellbrook.
Regards Lino.
