Subject: Phased Beverages! (was: EVE vs Beverage?)
Message-ID: <Pine.OSF.3.91.950820101356.30641A-100000@jekyll.sgate.com>

Hi Rich!

I use separate phased Beverage (note the capitalization, this is a 
man's name!) arrays on 160M, 80M and 40M.  (hey... why do u refer to 80M 
as 75M???  300 divided by 3.75 = 80  !!!  Or have ur SS interests caused 
to to forget about (80M!) freqs below 3900 kHz?)  

If u are planning to use a simple Beverage antenna, as opposed 
to phased Beverages, u can certainly use a 580 foot Beverage on both 80 
and 160.  A 580 foot Beverage antenna works very well on 80M although a 580 
foot Beverage antenna (not array) isn't long enuf to work particularly well on 
160M...    A pair of phased 580 foot Beverages with 270 spacing makes a 
fabulous 160M receiving antenna however, likewise a pair of 295 or 440 
foot Beverages with 135 foot spacing on 80M!   N2RM uses a pair of phased 
Beverages with compromise spacing that work well on both 80 and 160.

Here are some factors to keep in mind when selecting Beverage antenna length:

1.  As W1WCR points out in his Beverage Antenna Handbook (results easily 
confirmable with EZNEC), certain preferred lengths produce a very desirable 
"cone of silence" off the back of the antenna.  The preferred cone of 
silence lengths are (it is NOT necessary to use precision lengths, 
furthermore, ideal Beverage antenna length is somewhat affected by local 
ground conditions!):
160M:  290 ft,  585 ft,  880 ft,  1160 ft
 80M:  150 ft,  295 ft,  440 ft,   580 ft
 40M:  75 ft,   150 ft,  225 ft,   295 ft

2.  Longer Beverage antennas produce POORER front-to back ratios!  Beyond 
the minimum useful Beverage length (the first length in 1 above), about 3 to 
4 dB of front-to-back is lost each time the length of the Beverage is 
doubled!  As a result, the first two "cone of silence" lengths would be 
preferred if (but only if!) front-to-back were the primary design factor...

3.  Short Beverage antennas have a very broad main lobe, poorer 
response to low angle signals and lower sensitivity...  Of the four 
lengths listed under number 1 above, the shortest length has a 3 dB 
beamwidth of almost 180 degrees, not very desirable!  The second length 
has a 110 degree beamwidth (better, but still not good...), the third length 
has an 80 degree beamwidth and the longest length has very desirable 50 
degree beamwidth (but only 17-18 dB front-to-back ratio...).

The clear advantage of phased half-wavelength-spaced pairs of Beverages 
is that you get the front-to-back ratio advantage of short Beverages, the 
narrow beamwidth and sensitivity of long Beverages, and the fantastic 
front-to-side ratio resulting from the phased pairs that is unavailable 
with any single Beverage antenna length!

In summary: On 160M I'd suggest phased 585 or 880 foot Beverages spaced 270 ft.
On 80M the preferred phased Beverage lengths are 295 or 440 feet, spaced 135 ft
On 40M the preferred phased Beverage lengths are 150 ft or 225 ft spaced 70 ft.
N2RM's compromise of two 580 foot Beverages spaced 200 feet is a proven 
performer on both 80 and 160.
