The real challenge in the hobby is learning, and doing what you can with what you have. My home station consists of a inverted V at 30ft and my antenna tuner makes it work on all bands except 160 unfortunately.. as far as a VHF antenna goes, why do you say it doesn't transmit? If it's a good design fed with good feed line and at a decent height, it should work okay. My VHF home antenna is a comet 333 on top of the mast that supports the inverted V.. works great on two, 220 and 440. But I've done simple antennas like a quarter wave ground plane or a dual band mobile mounted to a bracket with ground radials on a chimney at the house in the past.. worked pretty good, even talk to the shuttle with it using an HT! Don't be afraid to experiment! That's the big thing in this hobby. Do whatever you can afford and learn from the experience. I've been in this hobby for 50 years in February and I'm still learning all the time! As far as antennas in a park, use whatever you can and whatever works. You don't need an antenna analyzer if the length is correct but it doesn't hurt lol. A tuner can be extremely useful for multiple band operation, but then multiple dipoles connected to the same feed line work just as well. You'll find some interaction between them but that's normal. Feel free to ask questions because that's the only way you're going to gain knowledge. Those of us in the hobby for a number of years are always glad to pass on our experiences and help.
