RF Cafe - Advertising Features & Rates for 2015
*** Please see the new advertising plan details below ***

RF Cafe typically receives 6,000 to 10,000 page views each week day, and about half that on weekends. RF Cafe is a favorite of engineers, technicians, hobbyists, and students all over the world. With more than 10,000 pages in the Google search index, RF Cafe returns in favorable positions on many types of searches, both for text and images. New content is added on a daily basis, and each week an XML sitemap is generated and sent to the major search engines. Daily additions on the homepage are broadcast on LinkedIn, Twitter, and Facebook.

Banner Advertising on RF Cafe in 2015Beginning January 1, 2015, with the exception noted below, advertising on RF Cafe is being provided by Google Ad Words, IHS (GlobalSpec), and Yahoo!|Bing Network. Please contact them via the provided hyperlinks for information; customer service agents are available for assistance if needed.

Private Advertising Options:

Honestly, having to chase down payments every month from some companies was a prime reason for stopping private advertising - it was taking too much time and was, frankly, annoying. However, if you would like to occupy a particular banner slot without going through one of the above listed ad services, beginning in April I will sell available slots in one (1) month terms at the following rates, with payment due prior to appearance.

The screen capture to the left is my current layout for RF Cafe. Your banner ad will be displayed exclusively in the purchased slot on every page of RF Cafe with every page impression (i.e., not shared). Prices listed below are per month, regardless of number of months. Please contact me if you are interested.

  • 768x90 (top): $2,000
  • 768x90 (bottom): $1,000
  • 300x250 (on specific page[s], except homepage): $150/page
  • 160x600 (top): $2,000
  • 160x600 (bottom): $1,500

I hate to be a pain in the posterior and do greatly appreciate past advertisers being willing to support RF Cafe, but this change is needed. Thanks for your understanding.


  • I do not collect page traffic or link click statistics. Your website server is a much better, true reporter of performance than I can ever provide.
  • You must supply the banner graphic (JPG, PNG, or GIF format), with a file size no larger than 60 kBytes. A hyperlink will direct to the URL you provide.
  • I'm pretty certain the page layout shown is representative of every page on; however, there is a possibility that a couple pages have been missed a template update.

  • I make layout changes from time to time to test performance, but regardless of the layout, your ad(s) will retain relative positional integrity.

  • Multiple month discounts are not available at this time.
