Searching for low profile mobile HF antenna

[KA3ULA]

Could anyone suggest a low profile mobile HF antenna? I am especially interested in the 39-42MHz range, but also want the antenna to be discreet. Any suggestions welcomed.

For that frequency range something like 5 - 6 feet is a 1/4 wave. That shouldn't be too difficult to manage.
