    Description

    Do you need a remote antenna switch? So why to pay a lot of money? Do it yourself!
    The size of the PCB is 99x99mm. (3.9"x3.9"). You can use SO-239 or standard flange mount  N-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 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 4:1 antenna switch.
    Kit contains:
    1) 1pc of double sided trough plated PCB with the solder mask for the HF (short wave)  4:1 antenna switch.
    2) 4pcs 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) 4pcs of 1N4007 diode
    4) 4pcs of S10K14 or S10K11 varistor
    5) 1pc of 6 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??)

    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 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 or FedEx shipping.   Thank you for the understanding and cooperation.
