Our mini 1/2w aerial range covers UHF and VHF frequencies, and includes wideband aerials.
Tuning guides can be found under the Resources tab.
Mini 1/2w Aerials
The mini 1/2w aerials feature a very small profile making them ideally suited for mounting on modern vehicles.
They are an end fed configuration which eliminates the need for a ground plane, so the aerial can be mounted in any position on a vehicle. It is also ideally suited for mounting on non-metallic surfaces.
The overall height of the aerial base is 80mm with a diameter of 16mm and is constructed from nickel plated brass with a black fibreglass centre section to house the impedance matching circuit.
The aerial is easily mounted by its 12mm stud, or onto a stainless steel bracket. Each mini 1/2w is fitted with 5 metres of RG58 coaxial cable as standard.
The radiating element is the standard 2.7 mm diameter stainless steel whip. The collinear element is formed from stainless steel wire with a black epoxy coating. This element is also available as a separate item (W1/2COL3).
The element cutting lengths for all models can be found under the resources tab. If further tuning is required, insert a reflected power meter in the feed line and tune the lower element for minimum reflected power.
In some installations it may be advantageous to raise the mounting position of the aerial, to clear vehicle body panels and improve the radiation of the aerial.
Each aerial is stamped to make identification of the model possible. This is located on the vertical bottom surface of the aerial body.
Different options include RG58 low loss or RG174 cable, a change to the cable length, brackets, connectors, or the base only and no whip.
Mini 1/2w Wideband Aerials
The mini 1/2w wideband aerial is an extremely versatile ground independent antenna, covering the majority of the VHF or UHF bands. With an industry standard PL259 base they can be easily field terminated, making them ideal for mobile vehicle installations and customers using channels across multiple bands.
The overall height of the aerial base is 80mm with a maximum diameter of 19mm, and is constructed from nickel plated brass with a black fibreglass centre section to house the impedance matching circuit.
The aerial is simply mounted by screwing it onto our SOB base. The SOB base has a thread diameter of 16mm and is easily mounted onto a stainless steel bracket.
Available in either nickel plated silver or black with a stainless steel whip.
These aerials come in three different configurations:
· Aerial only onto a PL259 connector
· Aerial onto a PL259 connector and a separate SOB base (order a SOB-58-SL with the aerial)
· Aerial onto a PL259 connector and a separate SOB base pre-terminated with 5m RG58 cable (order a separate cable SOB-KIT-58-5-UNT-NB-SL).
Use code BLK at the end for a black option instead of silver (SL).
