<p>Well Adam. So far nothing has changed, when propagation is very good we do get a weak signal, but it vanishes very quickly and is completely useless. The wierd thing is that it used to be the other way around with the higher channels having a weaker signal!!!</p>
<p>Anyway, I am building a new extended 2 bay Gray-Hoverman and this time I have very carefully cut it for 580 MHz. according to all my data this should give me a good signal on all the UHF digital channels from Waiatarua. Judging by the signal strength levels on the highest channel on my Panasonic TV, it SHOULD be really solid.</p>

<p>Now my Important question, where exactly are you situated? I am an experienced electronics engineer and have never had such a strange occurrence in all my 60 years in the business. It does make me wonder if the antenna or power on channel 29 at Waitarua has been changed? Looking at the polar diagram it is very</p>
<p>directional and out in the fringes it would not take much to drop the signal too low.</p>
<p>You will see that mine has dropped from 200uV to down in the noise at ~25 uV. All attempts to locate a receiver antenna fault have failed and the higher channels are coming in slightly better that they were.</p>
<p>Up from 250 uV to ~350. This is before the signal goes through a King Ray 24 dB low noise antenna preamp. "Curiouser and curiouser". I have contacted the radio licensing people and they have no info either though they did try to be helpful. Your posting is the first support I have had and exactly mirrors my experience.</p>

<p>Well I went up on the roof yesterday PM with my signal strength meter. On the higher channels I get about 650 uV (unamplified) which gives me a good solid result. But on channel 29 (538 MHz) i get a much weaker signal, about 100 uV. The weird thing is this though, when I designed my double extended Gray-Hoverman</p>

<p>Well I went up on the roof yesterday PM with my signal strength meter. On the higher channels I get about 650 uV (unamplified) which gives me a good solid result.

<p>I was getting a much stronger signal on the low channels with a single Grey-Hoverman antenna. Thus I designed the active element for 600 MHz to allow for the lower signal there. This worked fine for over 2 years,on all free view channels. It is only in the last week that this problem has arisen. BTW I am definitely using Waiatarua. Now I checked over the antenna extensively. My idea of a joint in the active element was not so. It turned out that I had already replaced the elements and must have been on my old single array.</p>
<p>Of course one of the problems of getting old (I am 77) is that I am not as capable of taking down the whole antenna as I was. If I could I would fabricate some new active elements for about 570 MHZ and install them. BTW does anyone have an idea of the active element to reflector spacing in the Gray-Hoverman?</p>
<p>I have seen several examples on line which seem to vary widely. At present mine is spaced about a half wave, but this might indeed be too great.</p>
