Not exactly a “hidden” antenna by any means – but you can get a lot of wire up in a hurry – I’ve put up 300+ feet of 18 gauge wire in a matter of minutes – if you are trying to be low key night time would be better – obviously – if conditions allow – and remember that electric lines are NOT your friend – Just Saying! . . .
Not too worried about a specific length for listening and you may want to use a 9:1 unun in the mix – drive a short ground rod in and use a little water to get a decent connection – it will make a difference as well.
If kites are not your thing – a 6 foot helium balloon or two will pull wire up as well . . .
