My limited experience with receivers suggests that the length isn't important,
in terms of loading, unless you're trying to get a very weak signal on a
specific frequency. If you cut the antenna to a "perfect" match on the
frequency, it won't be right for any other and receive difference between the
"perfect" length and a random length is negligible.
