The MPS-35 is an HF Whip antenna designed for general purpose marine environment shipboard applications. It is a vertically polarized end-fed monopole operating in the 2 to 30 MHz frequency band. The HF whip antenna can be operated singly for either receiving or transmitting applications. It can be paired with a second whip in a twin-whip antenna configuration and used for broadband purposes. It is suitable for mounting on ship decks and tilt mechanisms.

The MPS-35 HF whip antenna is a rugged, highly reliable, maintenance free design. Its general construction is all aluminum, fiberglass, and stainless steel, which enables it to withstand a marine environment. Its three piece tapered aluminum tubular construction facilitates assembly and installation. A vibration damping cable/spring is used to securely maintain the tapered tubes in compression and dampen the natural vibrations of the structure at frequencies encountered aboard ships. The base insulator contains three fiberglass drip shields to prevent moisture and other elements from shorting out the antenna element to the base. It is used with an appropriate coupler to match the whip impedance.
