[Repeater-Builder] Celwave Super Station Master UHF
Has anybody took the 1152-2 station master up in freq from 412-420Mhz to the 440Mhz ham band. I have new never used in the tube and want to bring up the antenna to operate in the 445Mhz area. Mike K7PFJ
RE: [Repeater-Builder] Celwave Super Station Master UHF
Mike, According to my Celwave catalog, the -2 suffix indicates that your antenna is already intended to operate in the 440-450 MHz split. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Mike Mullarkey Sent: Saturday, December 27, 2008 12:17 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Celwave Super Station Master UHF Has anybody took the 1152-2 station master up in freq from 412-420Mhz to the 440Mhz ham band.

Re: [Repeater-Builder] Celwave Super Station Master UHF
As it sits, it would have quite a bit of UPtilt on the 400 frequencies. That's not good unless your repeater is in a valley. Joe M.

Typo - make that 440 frequencies, not 400. Joe M. Mike Mullarkey wrote: Has anybody took the 1152-2 station master up in freq from 412-420Mhz to the 440Mhz ham band. I have new never used in the tube and want to bring up the antenna to operate in the 445Mhz area. Mike K7PFJ
RE: [Repeater-Builder] Celwave Super Station Master UHF
HI Joe, I know it would have a lot of up tilt and that is why I am wanting to modify it so I can run it at the 445Mhz freq area. I am sure someone out here has modified one and documented it.

Re: [Repeater-Builder] Celwave Super Station Master UHF
It should be a simple matter of trimming the elements to optimize it for 440. If it is in spec as Eric says, even better. Have you checked the SWR on it? Joe M.

You can always mount it upside down, works quite well generally. As it sits, it would have quite a bit of UPtilt on the 400 frequencies. That's not good unless your repeater is in a valley. _,_._,___

My apologies, I thought it was painfully obvious that you need to add a rubber boot to feed the coax in from the bottom (now the top) and drill a weep hole in the top (now the bottom) for condensation and draining. Failure to do this will of course fill the radome with water. We've done this with a Telewave and a Sinclair, not tried a Celwave, but I suspect it's quite similar. Good luck!
