2. 70-centimeter band - Wikipedia

   en.wikipedia.org/wiki/70-centimeter_band

   70 centimeters is very close to the third harmonic of 2 meters, which allows sufficiently broadband 2–meter antennas to be used for 70 centimeters. Antennas specifically designed to work on both bands are common. Also, 2 meters is far enough away from 70 centimeters to make diplexers small and simple, making it easy to cross-band repeat ...

3. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   (right) Fiberglass whip for 2 m and 70 cm amateur radio bands. The whip antenna is a monopole antenna , and like a vertical dipole has an omnidirectional radiation pattern , radiating equal radio power in all azimuthal directions (perpendicular to the antenna's axis), with the radiated power falling off with elevation angle to zero on the ...

4. Yaesu VX series - Wikipedia

   FM transmit on 2 Meters and 70 centimeters at up to 3 watts on 2 m and 2 watts on 70 cm with a 6VDC external source (1.5 watts on 2 m and 1 watt on 70 cm when using the internal battery) 1000 mAh lithium-ion battery; Internal ferrite bar antenna for AM broadcast reception; Stereo decoding for FM Broadcast reception; Stereo headphone connector

5. Amateur radio repeater - Wikipedia

   en.wikipedia.org/wiki/Amateur_radio_repeater

   Repeaters are found mainly in the VHF 6-meter (50–54 MHz), 2-meter (144–148 MHz), 1.25-meter band (1 1 ⁄ 4 meters) (220–225 MHz) and the UHF 70 centimeter (420–450 MHz) bands, but can be used on almost any frequency pair above 28 MHz. In some areas, 33 centimeters (902–928 MHz) and 23 centimeters (1.24–1.3 GHz) are also used for ...

6. Yaesu FT-817 - Wikipedia

   en.wikipedia.org/wiki/Yaesu_FT-817

   The selection has to be made per band (HF, 6, 2 m or 70 cm) using menu selection. The BNC connector is the antenna connector chosen when the relay is bypassed. A 70cm signal path goes through a high pass filter network, through the RF directional coupler/power detector (not on rx) to a low pass filter to a PIN-diode. In rx mode, these are ...

7. Amateur radio satellite - Wikipedia

   5.282 In the bands 435-438 MHz, 1 260-1 270 MHz, 2 400-2 450 MHz, 3 400-3 410 MHz (in Regions 2 and 3 only) and 5 650-5 670 MHz, the amateur-satellite service may operate subject to not causing harmful interference to other services operating in accordance with the Table (see No. 5.43). Administrations authorizing such use shall ensure that
