... which is a big Non-Code no-no. If anything ever happens in those buildings and it's traced back toward pretty much any non-code installed wire or equipment within the elevator shaft... you will need multi million dollar liability insurance. It happened to at least one very large Company I know about... now long out of business. s. We have done numerous installation of small in-building repeaters in high rise buildings in New York City. We drop cheap rg213 down the elevator shaft, securing it of course, and about every 3 floors install a T connector with a 1/4 wave antenna made of solid wire soldered into a PL259. works 100% every time, and so cheap to do.

Unless you pay very careful attention to the indoor antenna type and location you might easily receive a visit from the IMD Gremlin. Many types of 1/4 wave antennas in the mentioned situation can and do become very problematic sources. s. Ray Brown [EMAIL PROTECTED] wrote: Hi, Jim... I'm trying to do the same thing, to cover the interior of a 6-floor building with a LMR VHF repeater, and I tried suggesting a 1/4 wave mounted upside down as you suggested, and the Motorola guy scratched his head and said WTHeck? He was still trying to sell me a DB224 to cover the inside of the building. :-( Thanks for the confirmation! _Ray_KBØSTN - Original Message - From: Jim Brown To: Repeater-Builder@yahoogroups.com Sent: Monday, October 29, 2007 11:22 AM Subject: Re: [Repeater-Builder] KENWOOD TKR 750 Installation and problems-HELP!! One suggestion is to go to a simple ground plane antenna, and mount it upside down on top of your terminal building. The gain in an antenna will concentrate the radiation out on the horizon, which is not what you want. The upside down ground plane with no gain might be your best bet to have local coverage and have coverage directly beneith the antenna. 73 - Jim W5ZIT

Re: [Repeater-Builder] Daniel's repeater
Again, I highly recommend the Crescend amplifiers. If I remember correctly, they make the amps for Daniel's (the lower powered ones). Have never had a problem with their amps. I can't say the same for TPL. My experience is they provide Temporary, Problematic, Lack-luster performance. On 10/30/07, R. K.

RE: [Repeater-Builder] Daniel's repeater
If I may add my 2¢ worth I have a Crescend 150W PA on my 444.550 machine. It was purchased new and it was in service about a year before it released its installed volume of magic smoke. (The PA is protected by an isolator.) Anyhow, I took it out of the rack and back to Crescend, who fixed it free and returned it within a week. It is also nice that they are conveniently local to me Anyhow, they never asked me any questions about the installation they just took it and fixed it. They also continued the three-year warranty on the PA. (No, I didnt open the cover to see what happened I did not want to break the seal and void the warranty on the unit.) All-in-all, I am very satisfied with Crescend. My experience has been that they stand behind their product and provide excellent customer service when needed, so I am also very comfortable with recommending Crescend highly.

John Here they're not even allowing bases to be put in in the equipment room on the roof. Some places have even told existing equipment to move. It's not universal, but it is out there-be aware of it! But yes-the right way to cover in building without going to a full-blown system of amps and such is to mount the repeater and antenna as close to the middle of the building as possible. A local hospital had a certain two-way shop put in a UHF repeater (GR1225). They put it on the roof of the 16 floor building. It has coverage 15 miles away, where they don't need it, but a portable in the lobby, where they DO need coverage, is noisy. -- Jim Barbour WD8CHL

From what I've been able to see, Daniels is re-building Tait stations. The boards look nearly identical, just changed the front panels. Tait is made in NZ, and while the RF has improved a good bit over what it was in the late 80's, repeat audio is not very good compared to GE/MA-Com, Motorola, or even the Kenwood TKR's. Very mushy sounding. And they are cheap, maybe higher then a TKR, but not that much. If someone gave me one to play with, I would, but I don't know if I'd put it up at a commercial site.
