Hi All,<div><br></div><div>Continuing on my recent post about making my Nova-TD500 work properly, I have now observed the following.</div><div><br></div><div>1: HVR4000 = Perfect reception on all Channels</div><div>2: Nova-TD500 = Poor reception, barely watchable</div>
<div>3: HVR2000 = Reasonable reception, however TV3 is very bad or does not even work.</div><div>4: Set Top Box = Perfect reception on all Channels</div><div><br></div><div>Which makes me think that possibly it's "Dual" cards that need a better signal than a single tuner card, although to me it seems a bit unlikely.</div>
<div><br></div><div>Anyway, as I have identified that my antenna, antenna position and cable are all in average condition, I decided to do the whole thing properly and replace the antenna and possibly add a masthead amp.</div>
<div><br></div><div>I live in Te Atatu Peninsula, Auckland where UHF signal strength is supposed to be quite strong as it's close to the transmitter. Our house is fitted with a medium/low-gain antenna (kinda like this one, but maybe even smaller: <a href="http://www.freetv.co.nz/webapps/p/61418/52840/306850">http://www.freetv.co.nz/webapps/p/61418/52840/306850</a>). No masthead amp, no diplexer fitted (so just one antenna connected). However, an VHF antenna above it. Line of sight very blocked by a big and dense tree 10m from the antenna.</div>
<div><br></div><div>Now I'm not an antenna expert but I know enough about them to know these things can be quite critical. Simply fitting a high-gain antenna (a long one) with a masthead amp might just create a too strong signal. Well, at least with analog that was the case so I assume digital will have similar issues(?) so I'm wondering what the right plan of attack is.</div>
<div><br></div><div>If I look around the area, some houses have the really small antenna like we have, and some have a big high-gain antenna. I wonder if the big ones are placed because of similar DVB receiving issues? But they are a bit too expensive to just try it out. So I was thinking the following, in order of preference/trying out.</div>
<div><br></div><div>1: Get a medium/high gain antenna and mount and cable it properly. Get rid of the soon to be useless VHF antenna.</div><div>2: Put a mast head amp in. (I like the Kingray ones)</div><div>3: Relocate the antenna to the other side of the house which has line of sight and effectively divides the required cable length by 3 at least.</div>
<div><br></div><div>Are there any antenna experts here which can comment? </div>
