What sort of problems do you mean? Have you had any or are you a prospective purchaser?

Tell us more please Derek

HI thanks for the reply. I worded my message hoping someone had the same problems as my self more in line with the connections, the N/Connectors than the antenna, when we first installed the antenna we had quite a good signal but after a few hours we lost it we reconnected the N/Connectors now we have no signal.

Hi Derek, nothing to do with Radarama antennas, but I've had similar problem with poorly crimped N-connectors on other leads - are your's the crimped type?

dorsetderek · May 30, 2009, 07:45:37 PM

Thanks for that. no not the crimped type, the advise was to solder which I did, so I now consider the fault is with the N-Connectors, it seems that the antenna will only accept the N- type connector and thats fault rocketradio will be made be aware off, thanks for ininfo. DEREK

Hi Derek, if you fitted the plug(s) yourself, it would be worth cutting back an inch and refitting, it could be a whisker of the braid shorting to central - if you have a multimeter, check resistances outer to inner and end to end inner especially. N-connectors are the best for downlead connections at this frequency (1090Mhz). As a matter of interest what co-ax is this?

dorsetderek · May 30, 2009, 10:48:05 PM

RG213U 50 OHMS the very thick coax, yes I did what you recomend, but no joy, thanks D

Hi Derek, you have continuity end to end of central conductor, and definitely no short between inner and outer?

dorsetderek · May 31, 2009, 01:50:48 PM

Hi yes as far as I know, I have now decided to get another antenna, many thanks for your help. many thanks Derek
