Frequently Asked Questions

Does the HP2070 require tuning?
No. It is pre-tuned for the 2m (141–149 MHz) and 70cm (422–447 MHz) bands and is ready to use straight out of the box with no adjustment needed.

What connector does it use?
The HP2070 uses a PL259 (UHF Male) connector, which is compatible with SO-239 sockets found on most VHF/UHF transceivers and mount adaptors.

How is it mounted on the vehicle?
It uses on-connector mounting, meaning it connects directly to a compatible antenna mount (e.g. NMO, SO-239 boot mount, or magnetic base with SO-239 socket). No separate bracket is required.

What is the maximum power it can handle?
150W CW on VHF (2m) and 100W CW on UHF (70cm), making it suitable for most mobile transceivers and higher-power mobile rigs.

Is it suitable for TETRA or ORBCOMM use?
Yes. The HP2070 is listed as compatible with TETRA and ORBCOMM M2M systems in addition to 2m and 70cm amateur radio, provided the operating frequencies fall within its tuned range.

What is DC-ground and why does it matter?
DC-ground means the antenna element is electrically connected to ground (the vehicle chassis) via the feedline. This provides protection against static build-up and can help protect your transceiver from electrostatic discharge.

How long is the antenna?
The HP2070 is approximately 445mm (just under 18 inches) tall — a compact profile that suits discreet vehicle installations without excessive wind noise or visibility issues.

Is it compatible with a magnetic base?
Yes, provided the magnetic base has an SO-239 socket output. The HP2070's PL259 connector will mate directly with a standard SO-239 magnetic base.
