I recently purchased the CM 3019 uhf/vhf antenna, but haven't installed as yet. Does anyone know how the uhf portion performs compared to the CM 4248? I'm getting good results with the CM4248 and a preamp, but I needed the vhf. Now I'm thinking I should have gone with just a cut-to-channel vhf and kept the uhf-only antenna. I've done a search on the CM 3019 and not too much came up.
