I'm with Tevin on this one. A simple dipole cut to the calling frequency is the best solution. You don't need a tuner with a properly constructed one. Remember that a tuner only makes the antenna look good to the transmitter. The tuner may till see high SWR, but protects the radio. High swr means most of your signal is not getting out. OTOH a balun at the antenna feed point is essential.
For HF I use home-brew dipoles exclusively (no tuner) with excellent results.
One of the big selling points with the commercially made "porta-tennas" is that most of them claim to work on many bands. The hangup with that, in addition to not working very well, is that very few hams need/want/will use all the bands anyway. So what's the point?
It's far more productive to make a simple dipole that will work for real (without a tuner) for the one or two bands you use the most. Unfortunately, the status of amateur radio is such that there is an entire generation of Extras who haven't the vaguest clue how to make a dipole (something I was expected to do from memory as a Novice 35 years ago...and can still do today).
Regarding antenna tuners, they do have their place, but they seem to have morphed into a universal cop-out solution for any antenna problem and
de facto compensation for poor engineering and/or lack of skill. Again, this is what happens when too many people "earn" the the highest class ham radio ticket offered and the only dipole they've ever seen was a picture in a book.
In another topic I made this comment about antenna tuners, and it still applies:
"Antenna tuners...are not part of a carefully designed system. They are used to make a radio work with what would otherwise be an unacceptable load. With a few rare exceptions, adding an antenna tuner is, in essence, the same as admitting your antenna sucks...If you want an antenna that fits in a backpack and on its own will do no better than a 1.8 SWR, I'll throw something together and sell it to you for a lot less than what those glorified rubber ducks cost. "I can't top that. Everyone has to use their own judgement, and I understand I'm in the minority here. My experience says that the guy whose answer to every antenna issue is to slap tuner on it will always have an undeperforming station.
