Any help appreciated, Athol

to put it in one word RUBBISH
trouble is there is no such thing as an omni directional aerial for TV and 50% of the transmissions are in vertical mode and that aerial is for horizontal only.
This website has a lot about TV aerials
I fitted the DSE L4024 with the amplifier on that page and now have great recepton. That aerial does vertical and horzontal indepently in VHF or UHF. A digital set top box makes a massive difference in rural areas were they have fired up the digital TV. I believe all the ABC and SBS channels on digital TV are operational. The STB from Coles or Woolworths for $79 are great and sensitive tuner and work on 12vDC

Shaker WRONG the GME is not omni directional and suffers from the cardoid pattern. An aerial that suffers from the cardiod effect is NOT omni directional. I learnt all this when my GME did not operate satisfactorily and returned for credit. Read that website posted as what they have there is spot on.

hmm, thats disapointing actually, I was about to buy an antsig off ebay ($62). have a LCD TV/Monitor and wanted an easy to mount antenna on the roofrack for reception (as the standard screen aerial is useless)

Gday Athol,
Jeffrz@hotmail.com if your keen to part with it.
im interested, as there are limited types of aerials that will fit permantly mounted on roofrack.
live in a reasonably populated area...so dont expect it to work out on the tracks. and anything has to be better than the antenna on the LCD.

Shaker omni directional aerials do not work as described
they are poor performers and have a null position and a ratio of null to full signal which results from close to nil performance.
Omni directional aerials only perform in the horizontal mode and do not work at all in vertical.
while you may have been on boats with the GME aerial they have to be close to the transmitter and the signal needs to be in horizontal polarisation to receive the signal.
If you have an LCD with an external aerial the Anstig is such a low performer you will find the rod aerial on the LCD will probably function better in the majority of
places.
