Let say I want to run 2 Talking House or Ranger Masters I place both like 1.3 mile apart is that to close to each other??May 6, 2020 at 5:02 pm #114897ArtisanRadioParticipant

<p>The answer is…it depends.</p><p>It depends on the range you’re getting from the transmitters. If the signals overlap, then yes, they’re too close.</p><p>If you’re using 2 stock Talking House’s with the wire antenna, then it’s not likely that you’re going to see over a mile range.</p><p>If you’re using 2 Rangemasters, with great grounds, the right terrain and ground conductivity, audio processing, etc., then it’s possible, and you might see interference.</p>May 17, 2020 at 4:18 pm #114975CentinelParticipant

I’m in a congested, urban environment. I really couldn’t see the signal going more than a few blocks.
How are you getting your signal to the second transmitter?May 27, 2020 at 4:54 pm #115040DJboutitParticipant

I am just in the planning stage I do not know how I would feed the audio to the 2nd transmitterMay 28, 2020 at 9:33 am #115045ThelegacyParticipant

<p>Barix boxes may be your best bet to get the audio to the 2nd transmitter.<br /><br />As for Range in a Rural area with the Rangemasters each Rangemaster should get 1.5-2 Miles out. As far as a Talking House with the ATU you should get 1 1/2 miles with the ATU mounted outside 20 Ft up or way away from any obstacle but mounted lower so you can reach and tune it.</p><p>Under the Worst of conditions I get 1 1/4 miles out and this is a talking house with a 10 Ft antenna with an ATU.</p><p>So if your transmitter goes 1 1/4 miles till black you have to go another 1 1/4 miles from the faded black location before adding another transmitter. This way no whistles or anything beating against one another. Good Luck!</p>May 29, 2020 at 11:11 pm #115055radio8zSenior Moderator

Regarding the proximity of the two transmitters, please consider operating them on different frequencies. This will eliminate problems of constructive/destructive interference and audio delays.
Operating two transmitters within radio range of each other on the same frequency will result in patterns of practically unknown RF performance, especially when equidistant from each transmitter. Operating on different frequencies will provide extended coverage without these potential problems.

<p>The question really boils down to: are any of the 2 transmitters going to have a detectable RF signal at around 1/2 mile range (just to be safe – I’m giving 1/8 mile fudge factor).</p><p>If they don’t, then it’s perfectly safe to operate the transmitters on the same frequency.</p><p>Unfortunately, it’s possible that they will get that kind of range and even more. It all depends on ground conductivity, the transmitters being used, installation parameters, potential background and man-made noise issues, obstructions, etc. You can’t really say anything more than that – to say that you’ll get over a mile range without knowing these things isn’t being accurate.</p><p>If you’re using 2 Talking House transmitters with wire antennas installed indoors, then it’s likely that you’ll be OK. If you’re using 2 Rangemasters with outdoor installations, then you’ll probably run into interference issues.</p><p>The only thing you can really do is to try it out and see what happens. You can always fall back to operating on 2 frequencies.</p>
