KZJ COMMUNICATIONS ANTENNA

Post by loureed58 » Tue Jul 19, 2016 2:07 pm

Hi Group

I am very new to sdr but have managed to get a system up and running but it mainly only picks up FM Broadcast Stations due to the limitations of the antenna

http://www.ebay.co.uk/itm/SHORTWAVE-VHF ... SwaA5Wl25w

Does anyone have any experience with the above as it looks too good to be true to me (which probably means it is!). Putting up an external antenna in this area is a non-starter!

Kind regards

What sort of frequencies are you looking to receive?

You'd probably be better off with buying a cheap telescopic dipole antenna (e.g. bunny ears antenna) and mounting that vertically out a window.

You are correct in your suspicions. It is not up to the claims.
The question was asked. What frequencies? This is a critical question to ask if you want results.
The easy answer for the frequency an 820 dongles will cover is a discone as high as you can get it in as clear a location as possible. Sometimes life gets in the way and all antennas are a compromise. The discone is not a great antenna but it will outperform the one you are considering. Those on the forum are happy to help but PLEASE give us some details to work with. Such as where inside can you mount an antenna, attic, sealing in the corner- on what floor, neat a window, in the basement?
You have asked a very valid question that cannot be answered without details.
