I just bought an RF Explorer 6G so please forgive my newbieness on the subject.
It comes with a few different antennas and from the manual I can see that the extendable Nagoya NA-773 is the best choice out of those for frequencies under 1000MHz.
There is also an option to purchase a rubber ducky style antenna that is specific to 400-900MHz. I'm wondering how much of an improvement this will give if any over the stock antenna?
Without actually testing either, difficult to say, except that given it's [supposedly] optimized for 400-900, it should perform "better".
If I were to use a SMA to BNC adapter can I connect the RF Explorer to a Shure antenna distro system or daisy chain off a wireless mic receiver without damaging the RF Explorer? Would this require using a DC blocker? The RF Explorer 6G specs that it can handle up to a +30dbm signal.
If the RF output of the Shure multi-coupler or the mic receiver cascade has DC, then yes, you'll need to use a DC block. Depending on the model you have, it can take a maximum input of +5 or +10dBm, which is fine for connecting to a multi-coupler output (but do NOT connect directly to a transmitter). It would be a good idea though to have both 10dB and 20dB attenuators in your kit.[/quote]
