There are options for using a Hamstick or similar antenna for portable or limited space HF use. One is the Alpha Delta Outpost tripod:http://www.hamradio.com/detail.cfm?pid=H0-001639
It's very heavy, very
expensive, and very discontinued, but apparently HRO still carries it. Afriend of mine showed me his 10 or 12 years ago and I was very impressed with the performance, but also impressed that it weighed and costed about 8 times what it needed to.
So - I built one. I used 1/8" thick, 1/2" aluminum angle stock from a big box hardware store. For about $30 or so in materials and about 3 hours work I had something that weighed less than three pounds and fit inside a ishing pole carrier. I used it a number of times for portable operations with Hamsticks on several bands 20M and up, and they matched better than they did mounted on my car. Worth a try if you're even mildly handy.
