Do you need an antenna switch? So why to pay a lot of money? Do it yourself!

If you don't like PL (PL-259) connectors or you are afraid of the small power load of the N connectors, use DIN 7/16. Even if you use a cheap variant from Aliexpress, you will not destroy this connector on the HF bands. In addition, you get significantly better transmission and attenuation parameters than with PL connectors.

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 OM Power OM4000HF without any issue. 

Before you will select the right switch for you, check the parameters and compare.

Also look to my feedback, I sold hundreds of pieces all over the world without a single complaint.


In this auction, you can buy the BARE PCB  for 1:2 antenna switch.

The size of the PCB is 135x42 mm. 

Recommended aluminium BOX is Gainta G0247.

You will need those components:

3pcs of standard DIN 7/16 female flange mount connectors
2pcs of RTE424012 Schrack/TYCO 12V relais
2pcs of 1N4007 diode
2pcs of S10K14 or S10K11 varistor



The PCB is well designed for the minimum loss and the high RF power handling. 

With the delivered relays you can switch RF power >1.5kW CW/RTTY or 3000W PEP.

The switch can be used for 50MHz (6m) without any limitations.

This switch is for DIN 7/16 connectors. There is no other seller for this kind of product (in 12/2024).

If you find any, then it is a fake copy of my design. I made several iteration and measurement to
design the right PCB for the highest isolation, crosstalk and transmission loss. 


If you want to choose a switch from another manufacturer, always ask 

if the switch was measured at maximum power and how big it was. 

Also ask for measurements using a vector analyzer 

to show the transmission loss and isolation between the ports.

Thank you for choosing my products.


See my other auctions. I always combine the shipping.

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: 

Even the postal services are about 99% reliable, sometimes could be something lost. I do recommend using signed and insured letter.

Yes, it costs more, but you can be sure, that you will get it or it can be fully refunded. I am sorry but I cannot be responsible for a normal

letter. I cannot manage worldwide postal services. I do always my best, but when I post your goods at the post office, my role is finished.

Do not write to me, where is my ..... I want to refund .... etc. I am an honest man and if you don’t believe, please use signed and insured.

Especially if you are from Russia, Middle and the Far East, Italy and sometimes from the UK too. 

If you have selected economy shipping, without tracking. DO NOT OPEN THE CASE or ask for the refund!  You took a risk and I cannot do anything. 

I am giving you a possibility to get cheap shipping, but it is out of my control if it will be delivered or not.  

During the last time, there are several cases from Italy and Germany as well. It will lead to the strict requirement for signed and insured shipping ONLY (= more expensive for you). 

If you want to keep the low shipping fees in my auction, respect my rules, please. 

  

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 first working day after the purchase, 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.
