75xlt aerial upgrade

Postby Assassin of Silence » Thu Aug 31, 2017 3:16 pm

Hi, I'm using a 75xlt handheld scanner. It's working ok but I was wondering if upgrading the aerial would improve things ? I'm 30 miles from Manchester airport so would like to hear more from there but I'm also interested in picking up CB as I'm two minutes from the M6 and would like to hear any truckers passing through.

Could anyone recommend a decent aerial that would suit my needs ? Seen a few on eBay but not sure if they are any good or suitable for my needs.

From personal experience..I use a Watson 801 for everyday use,and Radioworld 881 for pulling in mil air stuff at home(it's far too long for outdoor use if trying to be discreet)I've used them on both my 75 and 125xlt,though to be fair I rarely use my 75 anymore,but that's only because it doesn't pick up military air.
Look at the Radioworld or Rocket radio sites,then at least you'll know you're buying from reliable sources.

The biggest decider on Manchester Airport is the terrain between you & it. Tall building & land rises could prevent you from hearing ground transmissions, even with a big improvement in antenna.

A longer flexible antenna will make a small improvement. But a outdoor antenna at height will make a big difference. You could also use something like a Nomad from Spectrum Communications.

http://www.spectrumcomms.co.uk/Aerials.htm

NOMAD WIDEBAND PORTABLE SCANNER AERIAL 25-1300MHz. The aerial element is made from 300 Ohm feeder configured like a Slim Jim, with modified stub matching to give greater operational bandwidth. It is intended to be portable but can be used as a permanent aerial in places where conventional wire aerials cannot be used. The overall length is 1.4metres and folds down to just 25cm (10"). It is fitted with 4m of 50 Ohm coax cable with a BNC male connector as standard, but can be supplied with PL259. For better reception of Air-band, 2m Amateur band or Marine-band use the Slim-G detailed above. Price £22.00 UK


The above would make a big difference, it can be hung in a window, or a corner. It can be hung in your loft permanently, or taken away for a weekend. A day at the coast or to the top of the local tall hill.
It can be hung or taped to pole.
However a Nomad will not out perform a decent outdoor antenna at height fed via decent coax. But it does make a very good plug & play alternative to get you improved performance on a handheld.

Thanks for your input, certainly a few options there. I'm picking up Manchester airport fairly well at home but getting little else unless I go mobile and get to higher ground. In the future I'll be rigging up a more permanent home antenna but for now I'll be choosing a better aerial to go mobile with ( in work van, wife's car or on my Harley ).

I'll look into your suggestions over the next couple of days and let you know which I went for :thumbup:

A small mico mag makes for a good temporary vehicle antenna. I brought one years ago so my daughter could operate her handheld from the back of the car better. But it worked so well, that I have brought several down the years. They only cost about £20 & are plug & play.

For my Velo, I have a period Pye Cambridge that now works on 4 meters & a small whip. And Nigel (M0CVO) often went to rallies selling his "Mighty Moxon" Antennas on his motorcycle & had a antenna up & working to demonstrate the antenna. So motorcycle mobile is not a massive issue.
A small roach pole (telescopic fibreglass pole) makes a good & easy to carry stationary support for a motorcycle antenna.

This site will draw the topography between your house and the airport.
http://www.heywhatsthat.com/profiler.html
If it is line of site without any obstructing hills, a higher antenna may bring in signals from the ground; but if the hills are too high, a higher antenna may be impractical.
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.

The first priority with antennas and getting a better signal is to get the antenna outside. A 'discone' antenna is a good all rounder and popular choice which works well on all the main bands from CB low vhf to high vhf and uhf.
