Demand for increasingly complex wireless communications devices means steady demand by the carriers for tower antenna space and services. A leading operator of U.S. communication structures is headquartered in Houston.

Crown Castle International (NYSE: CCI) operates nearly 24,000 towers and other communication structures, primarily in the United States. It leases and licenses antenna space on its towers to wireless communication companies and also provides such services as antenna installation, network design and site development. Clients include AT&T (NYSE: T), Sprint Nextel (NYSE: S) and Verizon Communications (NYSE: VZ).

The company pleased investors late last month, when it offered guidance for Q2 and 2007 earnings. In each case, consensus Street views were near the low ends of the ranges provided. The share price popped on the news and has since been consolidating the gain in a bullish "flag" pattern. Prices frequently exit flags moving in the same direction they were traveling when they entered them. In this case, that would be to the upside.

Brokers recommend the issue with five "strong buys," seven "buys" and four "holds." Analysts look for a 65% growth rate through the next year. The CCI Price to Book ratio (3.04), Sales Growth rate (72.80%) and Revenue per Employee ($794.2k) compare favorably with industry, sector and S&P 500 averages. Institutions hold about 79% of the outstanding shares. Over the past 52 weeks, the stock has traded between $30.42 and $37.69. A stop-loss of $32.30 looks good here. Note that the firm is expected to release Q2 results in early August.
