Vortex Antenna Systems V-RAT MKI [Remote HF 6-port Antenna Switching Unit]
We have a small number of MKI units for sale. These are the original V-RAT boxes. During 2016 we developed a top-end remote antenna switch with the assistance of a professional UK RF design company. The V-RAT (Vortex Remote Antenna Switch) had been designed as a heavy duty antenna switch, being able to switch up to 6 selectable output ports from a single input. 3KW power handling with 2 x 15A relays per port [30A total] and extremely good port-to-port isolation. Professionally UK produced laser-cut anodised chassis and enclosures. The normal online price was £399.00 – yours for only £309.00 [a saving of £90] – plus £30.00 shipping fully insured by courier for the UK. We also ship to the EU for an additional £50.00. Item is shipped within 1 week of order.

Vortex Antenna Systems V-RAT MKII [Remote HF 6-port Antenna Switching Unit]
We have a large stock of MKII V-RAT switch boxes available. In 2018 we decided to upgrade the original MKI version and the same professional UK RF design company helped design the board for us. The MKII V-RAT (Vortex Remote Antenna Switch) had been designed as a heavy duty antenna switch, being able to switch up to 6 selectable output ports from a single input.

The MKII version has totally new relays, using Fujitsu FTR K3 ‘wide-gap’ 25A relays. Power handling is a conservative 4kw and the unit exhibits extremely good port-to-port isolation.

**NEW MKII FEATURE: AUTOMATICALLY SWITCHED GROUNDING OF UN-USED PORTS**
The buyer now has the option to select un-used ports as being either ‘Open‘ which is the normal operating mode, or ‘Grounded‘ which is ideal for multiband antennas where the unused ports can be grounded by means of an internal jumper. Once the jumpers are set, automatic switching is achieved by an array of transistors and diodes making the whole thing seamless.

This is ideal if [for example] you have say a ‘5-Band Quad‘ on Ports 1-5 and a 40/80m dipole on Port 6. In this instance, Ports 1-5 would have jumpers enabled. This is really important [especially for multi-band quads] as you don’t really want the un-used Ports ‘Floating’ as it can affect the pattern and front to back of the active band. If the un-used ports are grounded at source – anomalies like this are unlikely to occur.

The unit has a professionally UK produced laser-cut anodised chassis and enclosure. The normal online price was £399.00 – yours for only £329.00 [a saving of £70] – plus £30.00 shipping fully insured by courier for the UK. We also ship to the EU for an additional £50.00. Item is shipped within 1 week of order.
