Do you need an HF to 50MHz 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.


In this auction, you can buy the KIT for this switch.
Kit contains:

1) 1pc of double-sided trough plated PCB with the solder mask for HF (shortwave)  2:1 antenna switch.
2) 2pcs of RTE424012 Schrack 12V relays
3) 2pcs of 1N4007 diode
4) 2pcs of S10K14 or S10K11 varistor
5) 2pcs of 2 pin terminal block

All components are new and unused. The size of the PCB is 49x100mm. 

This KIT does NOT contain SO-239 connectors!!!


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 from DC to 50MHz (6m) without any limitations. With the compensation coil (see the picture) is the loss nearly 0.0dB!!
It can be used for 144MHz too, but you must take into account the isolation and loss.

Recommended box is Hammond 1590B. I can be purchased at Digikey, Mouser, Newark etc.

Economy  shipping = normal letter, not insured, no responsibility of delivery. This is at your own risk!

Standard  shipping = signed and insured letter, with tracking number. Delivery is sure or you will get a full refund. This is the best choice for you!

See my other auctions. I always combine the shipping.

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. 

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.

 

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.
