octopus

i'm new to HF... and as i posted in a different thread i'm considering an MFJ Octopus, which is effectively a fan dipole. i have to choose 4 dipoles made of hamsticks to put in this - which will connect to my tuner. i was watching one of Dave Casler's videos (the man has taught me so much)...

i'm considering an MFJ2100 Octopus on top of a fence top rail as a mast... not sure how durable it will be when left outside long term, or how well it will work with my MFJ939 tuner... i originally wanted to get the CHA Spider, but they aren't currently being made and Chameleon says they won't...
