I know it's impolite to answer a question with a question (let alone a host of questions), but... What is this for? Do you need gain (directivity)? If so, how much? How much bandwidth? A quarter wave stub gives you broadcast coverage, with little gain and relatively sharply tuned. A logperiodic can give a lot more gain and a lot of bandwidth. A horn gives sub-octave bandwidth, but potentially more gain. Does the 30 dB attenuation have to be inherent in the coax, or can you use an external pad? Answer these questions, and I can tell you exactly what to get.
