RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Please refer to the screen capture below for Banner Ad, Highlighted Ad, and Hyperlinked Logo formats and locations. Banners and Hyperlinked Logos appear on every page of RF Cafe as shown. Hyperlinks point directly to your website. Please contact me if you are interested. Web page layouts do change occasionally, but order of ad precedence is always retained.
I keep terms simple and quality high.
NOTE: I reserve the option to refuse ads which I do not feel are appropriate for the RF Cafe mission.
3rd-Party Advertising Options:
3rd-party 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. Also, I only run 3rd-party ads as backfill and often none are running anywhere. At those times, the only way to be represented on RF Cafe is via private advertising plans.

Graphical Banner Ad Pricing:
All banner slots are set up to randomly display ads from 3 different companies, meaning your ad will display on average 1 out of 3 page views. Rates given are for occupying a slot at that 1:3 rate. Please read my research on AdBlock Plus to see how your banners will always display on RF Cafe, even for people running ad blocking software.
If available, you are welcome to buy more than one instance in a slot, which will cause your banner to be displayed more often. Terms include a minimum 3-month contract and up-front payment. All Graphical Banner Advertising plans include the features of the Maximum Exposure Ad plan.
Also, you may submit up to 3 separate banner designs that will all be displayed on average at the same rate in your slot. Each banner can have its own unique URL for a hyperlink back to your website.

Microsoft Animated GIF Software
Many moons ago, Microsoft created and released as freeware a handy animated GIF (AGIF) program. Since it is in the public domain for use, I have included a copy of the version I have been using for years (download it here).
I run Norton antivirus and can attest that the MS-AGIF.ZIP file is clean as uploaded, but I advise you check it yourself prior to use.
Note that one trick to significantly reduce the overall file size is to not use full-size multiple images. You can create a single full-size GIF file as the primary image and then create smaller files that are only the parts of the base graphic that needs to change, and then specify it (or them) as additional images and assign an x/y value for where they are to be located.
I have created a brief "How-To" page to help you understand the technique. It is an AGIF that I created for MECA Electronics.
