  • Our take on the Diamond Antenna D130J Super Discone Base Antenna

    The D130J is a wideband discone base antenna built from stainless steel and tuned to transmit on the 6m, 2m, 70cm, 33cm and 23cm amateur bands. Its real strength is receive coverage: the discone design pulls in a very wide swath of VHF and UHF traffic, from airband and public safety to commercial two-way and utility signals, so one antenna can feed several scanners or a wideband receiver. It handles up to 200 W on the transmit bands and mounts on a mast or pole, which makes it a common choice for a balcony or rooftop scanner setup. Compared with a single-band vertical it gives up gain and transmit focus, so it suits listeners and light VHF/UHF operators more than dedicated single-band work.
