SBS-1 antenna vs. AnRB antenna

[CZUL]

I have a quick question about antenna's. I'm currently using my SBS-1 antenna with the Airnav box due to the lack of an adapter. Is there any fundamental difference between the two?

Thanks

I would suggest that they are each fine tuned to be best with the device they were supplied with.  I have both an SBS1 and a Radar Box and have tried using the SBS1 aerial with RB but I dont get as many aircraft when I do that. However, I have not tried it the other way round (SBS1 to RB aerial) due to having no means to connect it. :-)
