[Repeater-Builder] Re: Celwave CC460-A circulator

Martin, I scanned the tuning instructions for a PHD460-C isolator and put it in the FILES section. The link is below. Tuning should be similar/same. 73, Joe, K1ike http://groups.yahoo.com/group/Repeater-Builder/files/Celwave%20Isolator%20Info/ --- In Repeater-Builder@yahoogroups.com,

RE: [Repeater-Builder] Celwave CC460-A circulator

The simplified instructions for tuning an isolator are: 1. Tune input (tx port) for maximum return loss with antenna port terminated in 50 ohms and reject load connected to reject port 2. Tune output (antenna port) for minimum insertion loss, sweeping from tx port to antenna port, again with

Re: [Repeater-Builder] Polyphaser Question

If you have a problem with a ground due to terrain issues, you might want to look into using Lyncole grounding rods. These are hollow copper tubes with a chemical crystal compound inside. The rod has some tapes around breather holes which you remove prior to burying in betonite clay etc.. The
