    Default stacking

    hi

    wondering if a splitter in reverse can be used to combine 2 or more ch 6-12 antennas to pick up ch6-12 all facing the same transmitter. if not does anyone have schematic diagrams to make your own stacking combiners to connect 2 or more ch6-12 antennas with all facing the same transmitter.

    want to have a go at stacking antennas facing the same transmitter



    got some sort of book but havent seen anything on stacking or couplers to stack 2 ch6-12 antennas facing the same transmitter

    Hmmmm!

    I think I've heard this question asked before in quite a few versions by the same person on various forums! Read through the ARRL handbook that you've been refered to previously.

    Yep.... with a multitude of user-names for the same person.

    The ARRL Antenna Handbook has been recommended to this person numerous times.

    This may do the trick but I have never actually used one!



    It has three inputs...

    Generally when stacking antenna one has to run a phasing harness in order not to create destructive waves at the common connection.

    Remember sine waves from form 5 physics, wave pools etc. sinewaves receivced at a common point that are out of phase (out of step)will combine and the resultant product can be something much less than you expect! Received in phase and they should combine to give you a greater signal.

    I have not played with the "splitters/combiners" but the magic is in the length of the cable that goes from each antenna to the input of the combining device.

    Normally TV antenna combiners are used with different antenna facing different regions or different bands (vhf/uhf) so the destructive out of phase condition is generally less of an impact.
