    Pictures linked below taken ealier this year, of the main deflector site for the Westport area, on the hill a few miles approx south-west of the town. These pics were taken just a few days before the deflector was due to go QRT forever (the 'plug was pulled' then and was blamed due to hugely declined financial support in recent years from viewers). Obviously the site had been made available to other users, the actual TV transmit aerials are just the two UHF panels mounted on a pole from the top of the mast. Two satellite dishes visible for receiving 4 UK channels (in times past it would have relayed another transmitter). This deflector also unofficially retransmitted analogue TV3 as well to many viewers who otherwise would not receive it, you can see a UHF aerial for receive of that from Truskmore.
    It was around dusk when the pictures were taken, they could be better.

    Areas of Westport town shadowed by terrain and so would have poor reception from this transmitter were served by another smaller deflector, which relayed the 5 channels from here.

    Picture link below is the picture of the low powered deflector I mentioned at Sandy Hill Westport.
    As is often the case with very low power setups (around 1 Watt ERP) domestic UHF grid aerials are used for transmitting horizontal polarisation, the two grids on top of the pole are transmit, whilst the grid lower down is to receive from the main Westport site of the above post.
    This deflector site was also hosting the FM 98.2MHz transmitter of temporary licenced 'Westport Radio' community station which was licenced for a series of Saturdays and Sundays last year, a Band II dipole for that is on the same pole as the TV aerials, whilst the MMDS-like mesh aerial on another low pole is to receive the uplink from the studio in the town. The 98.2 MHz transmitter was still transmitting with an unmodulated carrier during the weekdays (at least around the time this picture was taken).
    I have a few more pictures from the area, will post them soon

    May be wrong, but wasn't the RTENL relay (analogue) on Sandy Hill too?

    Yes, on an esb telecoms mast, pictures below. The UHF TV transmit panels approx one-third up the mast.
    The second picture below also shows the receive aerials (two Log-Periodic UHF).

    According to this:

    a transposer was first installed for RTE in Westport in December 1993.

    Have attached a few other pictures of installations on Sandy Hill, one pic has a view of Croagh Patrick in the background.
    The Westport church radio broadcast system also uses Sandy Hill to transmit - whilst these setups usually only transmit from the church itself, not so here - it uplinked using the audio portion of a small VHF Band III analogue TV transmitter at the church to link up to Sandy Hill from where it was (and I assume still is) transmitted on 104.8MHz. Outside of church times this transmitter (at least when I was in the area) remained on air transmitting 'white noise' from the uplink channel rather than preferably switching off !

    It's madness if the church is transmitting twice without a licence, especially when a legal alternative exists. Can somone in the area confirm or did you get the white noise very recently? I may be in the area later in the year and I will check if possible.

    Can you include a map link to the actual location?

    I have watched "Sky news" on UHF from here in the past.

    The deflector in Castlebar used to transmit Sky News.

    Has the Cbar deflector shut down yet?

    The site is located here: http://maps.google.com/?ll=53.795848,-9.519224&spn=0.001971,0.006539&t=h&z=18 I was in Westport on Friday and there was nothing broadcasting on 104.8MHz. The 98.2 station was on the air, carring the RDS name "TESTRDS1".
