OHHHHHhhhhhhhhhh don't know about that ----- well, considering its you, well okay then.
Please bare with me while I ramble on a bit, you'll no doubt pick out the bits you want, and that will be that. Anyway, antenna is constantly falling over due to its design, having those silly thin legs don't help, also fold as instructed and place on a flat card or board and ''watch' it fall over, you're actually watching for the low or high side of the tripod legs, the turret is normally shaped which means sometimes two legs are longer then one, using PVA glue very carefully dip each leg in, place the antenna (after obviously twisting the top round) on the turret, you will know by now which leg is longer or shorter therefore you should know which way round it will go and stand up straight. If it falls off again, DON'T remove the excess PVA leave it in place, re-dip those legs and attach, then you must leave it to completely dry. The big problem with PVA is once its completely gone off, you're be very lucky to recover any PE without destroying it first, the glue as I am sure you already know will dry clear, a little paint or weathering and no one will even know its there.
I hope this has gone way to answering your question. My wife often asks me why I write 10 words when 2 should do lol.
