JVP Argentina antennas - performance?
 

Hi:

Has anybody around here experience with the antennas made by
JVP Rosario, Argentina? I am especially interested in the
JVP250, JVP440 which look like the Sommer antennas - at least
at the first sight. The principle seems to be similar. No traps
and all elements phase fed.
I also would like to know if the manufacturer is responsive/helpful
when one needs spare parts.
The antenna design looks promising, as well electrically as
mechanically.

Kind regards, Eike
