Im having a few issues getting reception at my place in Klemzig. I was using a DSE amplified bunny ears for a while, which was workable but needed to be reconfigured for each different channel (i.e. "ears" in different attitudes). So this weekend i got my butt into gear and got an AntSig 162 antenna, as pictured here:
The site there seems to indicate that im smack bang in the middle of the green "good" reception zone (http://www.radiospec...TV antennas.htm
) and as such the antenna would be appropriate.
A quick search of the ABC site and the other PDFed site list shows that Mt Lofty/Norton Summit are my signal towers and that they are in the horizontal plane. So up on the roof i go and wire it all up, and point the sodding thing at Mt Lofty (well roughly since there is a tree in the LoS).
However im getting no reception apart from ABC, SBS and occasionally 7. Ive tried feeding the input through the DSE amplifier to no avail, and ive tried adjusting the antenna in poofteenths of degrees either way but nothing. My neighbours antennae are pointed in roughly the same direction, and they are fine despite the tree blocking LoS as well.
So im stumped. The one thing that has me puzzled is that i always thought that there needed to be some sort of resistance through the cable, but my multimeter shows that the tip and sheath are perfectly connected. I tested another couple of aerials and they are not.
The antenna had the balun preconnected to the array, and the wire is preconnected to the balun, presumably for idiotproof installation. However, where the balun is connected is a perfect shortcircuit through the antenna body. Is this supposed to be? I havnt looked deeply into antenna design since my highschool physics days, which is why im a bit rusty.
Any help would be vastly appreciated.
