Hf Antenna Switch, 4 Positions, 3 Kw Pep / Complete / Vk5rs / Matrix Only
VK5RS QRO REMOTE ANTENNA SWITCH 4-2-1 (HF + 6m). NEW IMPROVED DESIGN - ANTENNA MATRIX ONLY - NO CONTROLLER. Please note: This listing is for ANTENNA MATRIX ONLY - CONTROLLER NOT INCLUDED. PCB design is very simple with included RJ45 connector on board.
Plug in CAT5/6 cable from your antenna matrix to control box. Controller construction can be very simple (if you do not require all the protections in place) a simple 4 way rotary switch will do the trick. (switching 4 x positive feeds to relays). Connection diagram will be provided with your order.
Are you looking for an efficient and reliable way to switch between multiple antennas? Look no further than the VK5RS QRO Remote Antenna Switch 4-2-1. This hand-made antenna switch comprises an antenna matrix and a remote control box, which allows you to minimize and reduce costly multiple coaxes runs back to the operating position. 3.0mm RF tracks with. Only one antenna is active at the time; the others are all auto-grounded (if not selected).
We have tested the product using OM 4001A and can confirm that the antenna matrix can handle 3KW PEP power (at resonance). The cost of 2 Oz copper is 3x more than 1 Oz (Feel Free To Check on JLCBCP). LED CUTOUT - ANTENNA MATRIX. Please note that aluminium diecast housing can be customized to include LED cutouts to show the selected antenna. Please let us know if you do not want LED cutouts.
WITH LED CUTOUTS AS STANDARD. IF WE DO NOT HEAR FROM YOU. Switching of antennas within the antenna matrix is done by relays controlled from the control box (NOT INCLUDED IN THIS LISTING). We only use original OMRON. G2RL-1-E DC12 relays for our antenna switching.
All 4 antenna ports (on the back of the SO239 connectors) are shielded to prevent port cross-talk. TE Connectivity 2118709-2 32mm x 32mm shields are used. AIM Cambridge SO239 Connectors - Digi Key 116-25-7350-ND. Have been chosen for our antenna switch project. Made in Taiwan and manufactured in a controlled environment.(TESTED ON OM4001A 3KW SSB). SWR -The included sweep shows.
Whilst this antenna switch is. To be used on the 2m band, the SWR on 145MHz is 1.70, just for reference.
NEW slimline box - 150mm x 110mm x 34mm. Supplied and installed as standard. (refer to photos): SO239 connectors are elevated from the PCB with sufficient clearance between ground and RF tracks or, in this instance, the SO239 centre pin. 78db at 160m ; -50db at 10m ; -45db at 6m.
3 KW PEP SSB; 1KW Digi Modes. (providing that PTT is connected via the control box). YT Test video will explain the stated.
ONE - 15 cm CAT5 cable. ONE - RJ45 Female to Female Joiner. I can be contacted via QRZ.
