TV aerial ?

Help required re new TV aerial.

Bought a TRI-BOOM ULTRA HIGH GAIN, GROUP K. LABGEAR LAB450K.

Question is,,,, is it suitable for Freeview ? Getting confused with the usage instructions and reviews online.

Spec gives frequency, TV channels [21-48 ?] and other stuff which makes no sense to me 🙈

Or have I bought the wrong aerial ?

Thanks 🙏

TV transmitters are designed not to interfere with each other and are seperated by distance and frequency bands, A, B and C/D.
Each band has a specific aerial and there are also wideband and semi-wideband aerials W, E and K
Areial are also rotated to be Vertical or Horizontal, again this aids interference mitigation.

Each band covers a separate set of frequencies and is colour coded.
Consequently you need an aerial that matches the band (of frequencies) that corresponds with your local transmitter.
@TIGHTCHOKEposted a link above that will tell you what band and which direction/orientation you need to point your aerial.

A group 'K' aerial is a 'semi wide-band' device and covers the A ands B bands. It recieves them but nowhere near as good as a specific aerial.
Put into context it gathers about 1/2 the signal a dedicated aerial would.

To get the best result you need an aerial that matches the ransmitter.

Thanks for the input fellas, much appreciated 👍

Sorted now with the aerial for the Freeview,,,, would like to have Freesat as well, but that would mean cables coming in through the back of the house, extra to the existing in the front,,,, waaay too awkward 🙈😂

Hello, on the same subject, have to look after son and girlfriends dogs in September and he has no TV so I need a cheap indoor Ariel for my old Sony Bravia, only free view, any thoughts 🤔

We don’t have an arial due to being in a signal black spot so have freesat for the main TV - but in answer to your question the TVs in the bedrooms all use online on demand or catch up services. You can watch all the major channels ‘live’ as well (a few seconds delay). 
 

I suppose it depends if you like to ‘flick’ or watch the same things at the same time of day. 
 

i looked at indoor types and tried many. 
the magnetic car looking type. The flat a4 paper type and none worked due to the lack of signal / quality. 
they can be picked up on Amazon for £20 odd. Get your son to buy one and see if it’s an option before you go.
