Hi Robin, la night i went to search for more links for you and i posted but the message was awaiting for moderation and was not published. I don’t know if i did something wrong but in this case somebody has to tell me, i do not want to be forced to change nick for no reason. I’m 51 yo, sw radio enthusiast since age of 12 and ham radio licenced since age of 19, i made my first dipole 37 year ago and installed my first 3el. beam 35 years ago, and even if life sometimes make you change route for a while and sure that some 20yo guy in the internet age will know much more than me, i am not the last dickhead arrived here after reading that a dongle can be hacked for free.

This is what i wrote last night:

the most relevant article that i have found is from VK1OD; his website was removed but you can still read it here at the waybackmachine. Unfortunatly the pictures are missing but there is a video available on youtube here

As i said earlier another relevant test to support the idea that the feed line is part of the antenna system was carried from PA0RDT himself replacing the cable with optical line. It was posted on yahoogroups here but i could not access it so i read the transcription in the italian forum mentioned before.

So no matter how high is the antenna, if you put the receiver on the top of the antenna mast closed to the mini whip you have poor reception. No coax, no party.[end]

Now, put this on bold, my comment was not so inherent because ARA-2000 is for VHF and the wavelenght is much closed to the phisical dimension of the antenna while the mini-whip is for much higher wavelenght. Was i off topic? somebody could have told me why, but still what i said could be usefull for others
