New Antenna!

[BNN987]

Hey guys im looking to buy a new antenna, i know what kind of outdoor antenna i want but im wondering exactly what i need to install it and place it on a outdoor chimeny. i am getting it professionaly installed and i need to know what else i need, so far the antenna i have has the following specs Special Features:
• Ultra-wideband design 25 to 1300 MHz receive, 50-1300 MHz transmit (6m tunable for transmit)
• Compact and lightweight design enables antenna to be installed on balcony railing at an apartment or condominium
• Ideal for 2m, 1-1/4m, 70cm, 33cm and 23cm amateur bands
• Excellent "shop" antenna for testing various transmitters on a single coax
• Can be made further compact and lightweight by removing the top loading coil if 25-50 MHz reception is not required


Specifications:
Bands:25-1300 MHz
Gain dBi:2 (nominal)
Max Power Rating:144 MHz up: 200 watts 6m: 20 watts FM, 50 watts PEP
Height:5.6'
Weight:2.2 Lbs.
Connector:UHF
Element Phasing:Wideband Discone

A chimney mount is not the best choice. Is that your only option?

1) 2dbi means it has approximately 0.6db LOSS over a ground plane.

2) Mounting an antenna over a chimney will guarantee a short life for the antenna and the cable. At best, with gas heat, there's only very little sulphuric acid vapor coming out of the chimney. With oil heat there's a lot more.

3) Brick chimneys have just about 0 torsional strength. Newer wooden chimneys have even less.

Do yourself a favor and mount the antenna someplace else, and get something with more gain, like a Scantenna.

Ok will do so, also i didnt win that antenna on ebay. im looking for something just like the scantenna and i want to buy the antenna from something like PAYPAL so i can use my checking account (i hate credit card debts). I have no problem installing it i just need a good antenna and what i need lol..

Hi BNN and readers,

Beware of snale oil!

• Ultra-wideband design 25 to 1300 MHz receive, 50-1300 MHz transmit (6m tunable for transmit)

No such antenna exists in the real world, only in the minds of the advertizers and the gullable. The frequency response curve looks like a rollercoaster, OK at points of resonance with deep valleys between.

• Compact and lightweight design enables antenna to be installed on balcony railing at an apartment or condominium

Most scanner antennas meet these criteria except dipole types that can get a bit too long to fit without extending the mount past the railing. Then there is the possibilty the neighbors above and/or below will object to this funny apendage intruding on thier balconies. A discone would be a good choice, I think that's what you already have in mind.

• Ideal for 2m, 1-1/4m, 70cm, 33cm and 23cm amateur bands

Yup, I was right.

• Excellent "shop" antenna for testing various transmitters on a single coax

For Amateur bands you need the appropriate class license, for general on air testing of any transmitter you need a GROL. That's the first requirement, the second is an appropriate antenna tuned for each band segment you intend to test on, there is no compromise here.

• Can be made further compact and lightweight by removing the top loading coil if 25-50 MHz reception is not required

If that's the case any old discone will do, if you want 6M FM I recomend the Diamond, rugged and easily tuned. Don't forget those long cone elements, overall it's a pretty big discone, as tall as the afore mentioned dipole type is long AND the bottom is pretty wide too. One without that feature fits well on a balcony, this one is a bit unwieldy.

FYI, the Scantenna and it's clones ares a dipole types, see above. Before you buy look up the physical dimensions of any antenna.
