[TowerTalk] Reduced size receiving antennas

[Doug Turnbull]

It would be very interesting to hear how the DX Engineering Active Four
Square antenna compares to other receiving antennas.   Perhaps not a small
antenna as regards real estate but small by 160M standards and a lot less
space than that required by Beverages.   I have often wondered about this DX
Engineering product and have never seen a review or any comparison with
other antennas.

A Question, does it help to run a separate ground rod beneath a Beverage
which is installed over reasonably wet pasture land in a place such as
Ireland.   I would thing our ground conductivity is reasonably good.   Yes I
know that Beverages are supposed to really come into their own over land
with poor conductivity.   I am just trying to tap in to the knowledge
available on this forum.

Thanks to all.

A 4 square RX array is hardly small - for 160m it requires a minimum of a 
54' square.  Pennants and the K9AY look should work at a reduced size (their

size and shape is not critical) and it's likely better than no RX antennas. 
I've had good results on top band using a pennant.

I use the 4sq rcv array from DX Engineering and they work great.  They use
shortened whips for the verticals.  I do not have a full sized 4sq to
compare.

I have used other small loops in the past.  What I have found is something
is usually better than nothing.

TTers,

Has anyone built a reduced size version of the K9AY terminated loop(s)?

 If so what are the consequences (besides the obvious reduction in capture
area).

Same question for pennants and flags.

The reason for the question is a very long and skinny  backyard.

TIA and 73
