General Information

All filters are hand built to order.

 

·         Filters in the range between 430MHz and 1600MHz are enclosed in an ABS enclosure measuring 16cm(L) * 13cm(W) * 5.5cm(H). The physical size may change depending on the availability of hardware.

·         Specifications will also change from above depending on requirements and frequency.

·         When used on transmit, a note should be taken of the SWR before the filter is connected in circuit, also following the fitting of the filter. SWR can be matched by filter tuning. If this is not observed a transmitter fault can occur. This is also true if the filter is used beyond it designed passband frequency. Continuous monitoring of SWR is recommended as good practise.  YOU HAVE BEEN WARNED.

·         No responsibility will be taken for transmitter faults.

·         “N” or “SO259” sockets can be fitted to any filter, however above 400MHz “N” type is recommended.

·         These filters are passive components, no external power required.

·         It usually takes about 10 days to build a filter; progress reports will be given following order.

·         There are no serviceable parts within the filter. If the filter is tampered with the result will be damage to the filter.

·         Guide Price form amateur band filters is £90 plus £5 post and packaging.  (Correct as of Jan 2008)
