The HW series of half-wave, center-fed dipole and quarter- wave monopole antennas is now available with standard SMA connector terminations. These antennas feature internal counterpoises. They are available in standard center frequencies of 315, 418, 433, 868, and 916 MHz. The 868- and 916-MHz versions are half-wave center-fed dipoles while the 315-, 418-, and 433-MHz types are all quarter-wave monopoles. They promise to deliver an omni-directional radiation pattern with low VSWR. The rugged antennas attach using an FCC-compliant RP-SMA or standard SMA connector. P&A: $4.98 each in volume quantities.
