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.

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.
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.
