Depending on various factors, you should see at least 15db of attenuation between polarizations on a dual-pol antenna. Theoretically, you should see 20db. In any case, 15db is enough attenuation even on the same channel to operate two links reliably. -Matt Jason Wallace wrote: List, When

Sorry but this whole thread is going sour fast. 1. Dual Polarity antennas work for transmit and receive. They are not TX only or RX only in configuration. 2. The normal isolation between vertical polarity and horizontal polarity can range from 10-30 dB depending on the operating

Bob, Item 4 is what I am talking about. If your radios have very good adjacent channel rejection, are not transmitting at high levels, and the antenna has minimized any of the coupling I mentioned, then they may be able to listen through the noise from the other transmitter. A lot of this

Ah..Lets do some math... Lets say the radio has a +20 dB output. For this example there is no line loss. The antenna is rated at 30dB x-pole isolation. Here we go... +20 dB -30dB xpole = -10 dB receive level. In my book that is high enough to kill any link of the same freq on
