| Antenna Switching | ||||||
|
||||||
| At DF3CB we have 9 antennas that need to be switched and distributed to two (or more) radios. Besides that the tribander must be able to be combined with the monoband yagis. The perfect solution turned out to be the microHAM Double Ten Antenna Switch and the microHAM Stack Switch. | ||||||
|
||||||
|
The microHAM Double Ten Switch™ is a high performing, high power rated, high isolation, rugged remotely controlled antenna switch. It can handle ten antennas to two radio outputs. The switch has a very high inter-station isolation. |
||||||
| The microHAM Stack Switch™ (on the right) can match (and switch) up to three antennas to two radios outputs. Any combination of the antennas can be switched to the main output and any single antenna can be switched to the sub output. I use the STACK SWITCH™ to combine the KLM KT34XA with the 20m, 15m and 10m monoband antennas to be able to transmit and receive into two different directions on these bands. | ||||||
| I had several reasons to choose these products: | ||||||
|
||||||
 |
||||||
| The Stack Max™ controller is a microcontroller based push-button controller. It features a push-button operation together with a (optional) remote operation from computer with latest technology and configurable choice of special properties of phasing or stacking. | ||||||
| The Double Ten Switch™ and the Dunestar Bandpass Filters are switched by a home-brew antenna selector - either automatically through the band data outputs of the FT-1000MP's and band decoders or manually with two rotary switches (Radio A/Radio B). | ||||||
 |
||||||
| The box houses also a preselector and a 160m bandpass filter for receive. | ||||||
 |
||||||
| The band decoders are W9XT BCD-10 decoders. | ||||||
