You might have noticed in the last picture in the blog, not only was there an MA5B on the mast, but I also have a quad 70cm omni array.
The aerial was spotted in the back of a pickup truck with a whole load of ex-PMR stuff, and was purchased at the princely sum of £35. Bargain!
This was part of the plan to develop the 70cm side of transmission for GB2RS, the news broadcasting service of the RSGB, which i read for most Sundays. I have been using a duplexer to simulcast from two transceivers on my colinear, but the opportunity for a catastrophic failure was huge, with a fault developing on the duplexer possibly dooming either of the transceivers to meltdown! It would also allow me an opportunity to run maximum UK power on the array, which could handle it easily without melting! This is something the colinear could just NOT do.
I am now looking for a serious UHF linear, which is not going to bankrupt me. If you hear of anyone that has one for sale, please let me know.
