I agree a small 2m 440 antenna and it is not worth the price.As jonwienke points out, it looks like it's just a dual band (144/440) ham antenna. Will it receive down to 500 Khz? Sure it will. But it will be horribly bad
It's only 3.5 feet long.. There's really not enough there for decent reception on HF frequencies. But for the Aircraft band (118 Mhz) and up, it will probably be adequate.
Edit.. I just looked again and see the price is $212 dollars US and the shipping is $58 US (For a grand total of $220.00) . That's nuts.. Do not buy this antenna!
