Great start. I would regroup products though. It would be my thought that many visitors to your site may not know all required for each system. I would group as:
FTA - DVB MPEG2
Satellite Dishes
lnbfs
Motors
Receivers
Complete Systems
And so on. Maybe make a main heading of Satellite Television. List the subcategories in alphabetical order. So under Satellite Television you would have:
C Band, DirecTV, Dish Network, FTA - DVB MPEG2,
Globecast. Each broke up as exampled above.
Same for Radio and so on. Somehow work switches and misc into each category. The human mind groups in groups of 5 or less. So you want to avoid numbers like 6 sub categories. This forces your visitor to think and thus making the visit somewhat uncomfortable. They will group into 2 3's mentally. Listing alphabetical is an automatic list arrangement for human thought. Easy to follow and locate info in.
As to search. While a great feature to have and easy to incorporate with a db driven site it is your primary focal point on the main page. Perhaps making it the first on the list in the products menu and downsizing the physical size. Utilize the space currently held for search for perhaps a rotating spotlight product area. Create a small flat file with info as to products you want in the rotation and everytime someone visits that page a different product pops up. Linked of course to the appropriate info page for that product.
Use some form of seperator in your menu to keep main groups seperate. Something as simple as a block of color. Example. Dark blue head for main category with a light blue area for sub categories. Follow this color scheme into that area of your site. As for DirecTV and Dish Network I would use their established colors in their respective areas.
Just some preliminary thoughts
