Is there any external antenna that does not overload or desense the trx2 on p25 trunk?
Anyone using an external antenna with their trx2 for p25 trunking?

That is what Attenuation is for. I have a 2 tv antennas with a signal combiner and 2 amps that I use for OTA tv and my scanner...I use attenuation setting in ezscan on some frequencies and I use the ATT button over all.

I did try attenuation, no joy. Using the stock antenna, the P25 phase 1 systems are ok, but NXDN and conventional vhf / uhf have reception issues. Using the external discone helps everything but the P25 phase 1 systems. Stand alone discone on a stand alone mast.

I think the external antenna picks up local noise that disrupts the rx of the stand alone (non LSM) p25 phase 1 CC's. Moto type2 TRS and single site P25 phase 1 VC's receive good.
