Gainflex antenna question

Georges,
Not enough information in your post,(you didn't say whether its a transmitter or receiver antenna which is in question here) but a receiver antenna which is cut for 433 mHz will probably work OK for the low end of the 435-470 mHz spectrum, but won't be as dependable or efficient if your base is transmitting in the higher end of that range. Much depends on the xmit antenna, in terms of gain and height. A unity gain antenna at the base, combined with as much height as you can put on it, will usually cover most RTK needs. Remember that in these frequencies, line-of-sight between base and rover antennas is everything. Cut your antennas for the middle of your assigned frequency range, that's the best you can do.

I'm not familiar with GainFlex antennas, but basically antennas are antennas and radio is radio and a certain set of principles applies to all. I'm just assuming that you are asking about RTK radio data links here. Again, not enough information in your post. Can you elucidate further on your problem?

Hello,

RTK radios, satellines on a Leica GPS900.

I am receiving loaner Satelline radios (433 MHZ) without antennas. My present radios are 466 MHZ. The antennas that I use are rated from 440 to 475 MHZ.

So I will be using the 433 MHZ radios with those upper frequency range antennas.

I was just wondering what the effect could be.

Thanks,

Georges
