I'm not exactly sure what you're looking to do, but I have the TYT UVF1 that I added a speaker mic to and usually run it in the base a dual band antenna. That will definitely improve your range. I also have limited funds, and if not for the generousity of others at Xmas, and a few good Ebay sales of my CB equip, I'd be pretty much limited to the HT on the antenna. It does a surprisingly good job. If you're looking for a really inexpensive base antenna, check out the radio shack model 20-176. It's a scanner antenna, but it works very well for dual band HT's. I used it all last summer and fall until I got a real dual band antenna. Mounted up high, it's a big improvement over the rubber duck. And don't tell anyone here on the forum, but I used it with the cheapie Radio Shack coax.
Long story short, I cleaned up my signal on the closest repeaters, and reached a few others I couldn't before. Total investment was about $50.00. Oh yeah, and the mast was 1" or 1 1/4" PVC conduit. It swayed a bit in heavy wind, but only cost about $3.00.
I may have some pics somewhere.......
P.S. Expect to replace the speaker mic every couple of months. Had a Wouxon model that broke, a TYT model that broke, and a Wouxon I got in March that is already finicky......
