Yep. 2 separate WRAP boards in 2 separate mini-box metal enclosures. I have had a look at the spec sheet for the RadioWaves antenna's but they don't mention any isolation between the horizontal and vertical N-Type ports. Have you used these particular antennas before? -Original Message-

Indeed and this seems to be what is happening with my RadioWave antennas. I did ask about this prior to purchasing the antennas and was assured by the vendor that there was isolation between the ports. Testing suggests otherwise. Has anyone else used dual-polarized RadioWaves in this way? If the

I'm not saying there isn;t a benefit now and then sharing a Dual pol antenna between two freqs, otherwise nobody would make them. BUt We have found most tower agreements also, have restrictions in the agreement that disallow using multiple radios our spectrum ranges on the antennas

List, When antennas are separated by normal distances, they can only see each other electromagnetically (ie, radio waves). However, when they are close they will experience capacitive and inductive coupling. Dual pol antennas work fine when only receiving (as in those large satellite

Hi Tom, Our tower rentals are all based on wind-loading so a dual-pol antenna costs the same as a single pol. What are the advantages of using both polarities for the same signal in a good LOS environment? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On

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

Just checked the specs for the RadioWaves antennas that I'm having the problems with and see that they have 28dB X-Pol. Rejection would this suggest that the circuitry controlling the 2 feeds are separate? If so, is there anything else that could be preventing us having 2 separate simultaneous

Reading further through the RadioWaves docs it clearly states that each polarization is isolated from the other so I'm guessing the issue isn't the dishes or feeds. The radios are mount about a foot from the dishes and the RF cable is LMR-400. Is it possible/plausible that the interference is

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
