Do you need a remote antenna switch? So why to pay a lot of money? Do it yourself!
The PCB is designed to provide the best isolation and power handling. This switch has the highest isolation between unused antennas inputs and output.
The power handling was tested with OM4000HF without any issue. Before you will select the right switch for you, check the parameters and compare.
The PCB size is 150x150mm. (5.9"x5.9"). You can use SO-239 or standard flange mount N-connectors.
You can mount the connectors directly!! to the board with 4 screws. This is the best solution ever!
You can not find here similar design (if yes, it is copied from me without the permission).
In this auction, you can buy the KIT for 6:1 antenna switch.
Kit contains:
1) 1pc of double sided trough plated PCB with the solder mask for the HF (short wave)
6:1 antenna switch.
2) 6pcs of high-quality RTE424012 Schrack 12V relays (more than legal power limits capable, relays are made in Austria, it is not a Chinese scrap!!)
3) 6pcs of 1N4007 diode
4) 6pcs of S10K14 or S10K11 varistor
5) 2pc of 4 pin terminal block
All components are brand new and unused.
The PCB is well designed for the minimum loss and high RF power handling (tested for legal limits and more).
With the supplied relays you can switch RF power >1.5kW CW/RTTY or 3000W PEP.
The worst isolation between input and output is at 28MHz at the -69dB level.
The worst loss is also at 28MHz at the -0.05dB!!!!
(Do you know any better switch??)

Attention! Recently, several vendors with counterfeit my switches have appeared here.
My design was developed in 2014 and since then, several hundred of them
have been operating around the world, without complaints.
If you want to choose a switch from another manufacturer, always ask
if the switch was measured at maximum power and how big.
Also ask for measurements using a vector analyzer
to show the transmission loss and isolation between the ports.
My auctions contain this information automatically.
Thank you for choosing my products.
Warning for buyers from Australia. Shipping time to Australia is between one and three months! If it seems like a long time, don't buy my goods or order express shipping. In any case, I recommend standard transport with insurance and tracking of the shipment.
Important information and terms and conditions:
DO NOT BELIEVE eBay's estimated delivery time!
eBay does not know Czech or Worldwide postal system well.
The delivery time is sometimes faster than proposed by eBay, but very often is slower (especially for overseas shipping and the UK included!!).
I am trying to do my best, in 90% I am shipping fast, but the delivery time is out of my control.
If you are in a hurry, ask me in advance and I will send you an offer for EMS shipping.
Thank you for the understanding and cooperation.
