It is really awkward set up where i am. Garden is to small to lay out the aerial. I have to pull it apart then assemble bit in the gap behind the house laid out across a set of chairs.
Sigma claim that carefully set up Plus kit you should get a decent swr with an internal tuner.
Withe regards to the 450D you will definetly need an external tuner for 11mtrs. You can hear loads but dare not transmit as the swr is a bus ride out. Just ordered an LDG z 100 plus tuner tk work with the 450D.
Will let you know how i get on
