Holland Electronics line of Ground Blocks utilize their popular G-F81F to insure the best connection available. Hollands G-F81F is the one of the highest quality F81 adapters available on the market today. Holland's Patented Pin seizure mechanism offers twice the pin contact area and holding force as compared to conventional F splice adapters. This allows for the higher current handling required by newer satellite systems and offers long-term reliability.

Advantages of Holland's Premium Design Lower Insertion Loss The G-F81 series has approximately 1/3 the insertion loss of standard splices at higher frequencies.(Savings of over .5 dB at 2 GHz). Higher Frequency Operation The internal air dielectric in combination with the symmetrically round pin provide superior matching over wide frequencies between DC and 3 GHz. Higher Return Loss With a return loss of over 35 dB @1 GHz, as compared to 13 dB for standard splices, the G-F81 can assure a higher match resulting in faster digital speeds. The G-F81 series exceeds current SCTE minimum RL levels of 20 dB.

Flat Port Ends The G-F81F series uses a patented method to provide flat ports ends on both sides meeting the SCTE specifications of flatness and aperture. Patent # 6,113,431. Round, Multi-Point Seizing Pin The patented multi-point seizing pin provides a larger contact area than standard, dual flat pin splices. This results in lower contact resistance and thus higher current handling capability when needed, as well as a greater resistance to long term center conductor oxidation. The patented design also creates a mild wiping action which removes a few microns of oxidation upon insertion. Beryllium Copper Seizing Pin The use of the more expensive beryllium copper material for the center conductor seizing pins insures a greater holding force than the traditional phosphor bronze or copper pins used in standard splices. The advanced material also maintains a higher spring tension over repetitive insertions. Accepts a Wider Range of Cable Center Conductors Due to the greater elastic capability of beryllium copper, the G-F81 series can accept a wider variation in cable center conductor sizes and maintains its high strength on the smallest cables even after repetitive insertions of the largest cables.
