[TowerTalk] Re: Cable entrance...

Wed May 19 14:00:30 EDT 2004

Hi All,
Well, if you are spending a lot of money in buying Heliax cables (7/8, 1 
5/8!!!) then I do recomend you to invest also in a good "Cable window" + 
boots. you can give a look the following providers:
(I am working with celullar networs and we use this brands)
*Andrew: give a look to catalog #38 www.andrew.com
*Fimo: These are made in italy, excellent brand and quality as weell.

You will aldo find "grounding kits", "Grounding Bars", hanging, etc, etc

Good luck with your Broadcast!!! :o)
