The Arrow OSJ-146/440 is a dual band J-pole. It is rated at 1000 watts, is well made, and is less than $50.00. It can be put together in just a few minutes. I have been using mine for years now and I have an SWR less than 1.5 across both bands.
Currently I have this antenna in my attic due to deed restrictions. I built a simple stand with PVC pipe. This setup is very lightweight and easy to move around. The whole antenna including the stand and coax cost less than $75.00.
