As a postscript to the RF Systems DX-1 Pro active whip antenna comments I made, WRTH did an extensive review of various active whip antennas perhaps 5 or more years ago. The DX-1 Pro was clearly

Hi, I'm familiar with the circuits used in the head end of the older DX-1 Pro, and the receiver coupler/supply. The head end is a basic high-impedance active whip antenna. The circuit is an exact

Wellbrook antenna: is the loop shielded? I am guessing maybe not, since its performance still seems to be good into the VHF range. IF not - will shielding such a loop, be worthwhile to diminish

Dear Fraser In this case for direct feedthru I guess I un-tract my retraction (LOL again) smells like a Norton amp with this gain range ie 8 to 12 although with higher turns can get to near 20 however

Hi Paul, Thanks for the input. The DX-One base unit has unusual calibrations on the attenuator. Instead of just showing the inserted attenuation it shows the system gain. The +10dB position is a

Hi Fraser and All sorry scratch all that I just transmitted the 10 dB is the antenna alone LOL oh well Paul

Hi Fraser, I hadn't thought "polarization fading" to be a big problem, although a real phenomenom, else every antenna since Marconi would have been egg- shaped I'm thinking. I'm no expert, however.

Dear Fraser had a look and look at the specs I think there is a big clue in the gain as it is only 10 dB to me that indicates a David Norton Noiseless Amplifier and likely very close to what Dallas

CORRECTION..... it. OOOOPs, I forgot the url for Universal ! Here are some urls related to the DX-1 and a review :-) http://www.universal-radio.com/catalog/sw_ant/1246.html

Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the loopantennas group. File : /dx1.pdf Uploaded by : frasercastle

Ref the DX-One and "what is it" I see that Universal sell it so there web site gives a good view of it. I will upload the PDF instructions and specs to the files area for Group comment. Cheers Fraser

Hi All, A new question to ponder for the Group. I own an RF Systems DX-ONE Pro MKII and have tried to establish exactly what it is from the manufacturer.... they are staying silent :-( For those not

Click! (and save web page) The higher-resolution image obtained then zooms quite well in Irfanview - it looks a bit blue-fringed, like a slightly out-of-focus scan of a ballpoint pen original, but

Allegation of involvement in a conspiracy is not what I would call "civil" - more like "civil-actionable". How fortunate for Mr Ikin that he put his allegation into a private email and not publicly to

Patrick, I couldn't agree more :-) Fraser
