I have an X-300 which used to work well but has been stored away for 3
years. It has now been erected well in the clear and fed with good coax.
SWR is good on 70cm and very good gain but SWR is high on 2M, causing power
foldback on the TX. Anyone have any idea what could have gone wrong? The
internal element loks good and the centre joint OK.
