I am currently living in Gothenburg, Sweden.
I have recently aquired an old BSB dmac squarial of which I would like to use only to receive radio from the analogue astra group through an equally old Amstrad SRX100.
I understand the squarial is RH circular polarised so I need to convert it to the HV type.
The principal reason for all this bother is the need for a very small and flat receiving dish where it shall be used.
Alternatively could you suggest any low budget options.
Thankyou for you help.
I haven't seen a "squarial" for 8 years but I can confirm that it is circular polarised and I believe the "LH" could be changed by swapping over a film inside? Never done it so it means nothing to me. You can't, of course, convert the matrix to H/V.
Small square antennas are never "low budget" options. If you want "smaller" then you pay a premium for optimised performance. Technisat sell a very expensive square antenna - or used to. You could paint it so it looked like a fold-up table.
BTW, if you use a smaller-than-normal dish, you will need a *very* sensitive receiver to compensate. An SRX200 with a tuner threshold of 8dB does not fulfil that requirement! In addition, it is unable to tune all the available audio frequencies.
