<div>The tech got back to me with the following:</div>
<div> </div>
<div>"Antenna Gain is going to be 3db to start with but then unity when we get around to putting the 2m repeater up there , HAAT not <br>sure what it means but antenna hight is 83m above ground or 883m above sea level"</div>
<div> </div>
<div>Sound about right?</div>

<div>G'day Ray - project is on the move again - the GM300 has been repaired and aligned and I have taken a look at the digi_ned link you sent regarding PHG and I'm sure we can add it as soon as the tech tells me the HAAT and gain of the antenna.<br>
</div>
<div>At this stage I have to program up the Foxdigi witht he site info and post it away to the installer who will get it up on Nardi next time he is workign at the site.</div>

<div>Hopefully this'll kick interest along and we'll get some others up in the months to follow.....</div>
