Connectors... what type? Heliax, coax, audio, DB25s, ? You'll need two connectors for each piece of cable you use, one at each end. What exactly are you asking? If it's just on the antenna system, and it's for a garage repeater, and a 20-foot mast, you may be able to get by with 50 feet of RG400 and six connectors... one run from the antenna to the duplexer, a second from the duplexer to the receiver, and a third from the duplexer to the transmitter. If you have a circulator in line add two more connectors. If it's a serious RF site with a 200 foot tower, it's another, larger and more complex can of worms. Have you read this page? <http://www.repeater-builder.com/rbtip/checklist.html> My own opinion it to NOT reinvent the wheel. Offer to help a wheel mechanic and learn that way. In other words, get to know the local repeater people and tag along with them as they work on the local systems... Buy them lunch. Pick their brains. You will learn a lot by asking them "why is it done this way?" Mike WA6ILQ
